+# Changelog
+
+## Changes 4/19/2025
+
+- **Extended “Remember Me” cookie behavior**  
+  In `AuthController::finalizeLogin()`, after setting `remember_me_token` re‑issued the PHP session cookie with the same 30‑day expiry and called `session_regenerate_id(true)`.
+
+- **Fetch URL fixes**  
+  Changed all front‑end `fetch("api/…")` calls to absolute paths `fetch("/api/…")` to avoid relative‑path 404/403 issues.
+
+- **CSRF token refresh**  
+  Updated `submitLogin()` and both TOTP submission handlers to `async/await` a fresh CSRF token from `/api/auth/token.php` (with `credentials: "include"`) immediately before any POST.
+
+- **submitLogin() overhaul**  
+  Refactored to:
+  1. Fetch CSRF  
+  2. POST credentials to `/api/auth/auth.php`  
+  3. On `totp_required`, re‑fetch CSRF *again* before calling `openTOTPLoginModal()`  
+  4. Handle full logins vs. TOTP flows cleanly.
+
+- **TOTP handlers update**  
+  In both the “Confirm TOTP” button flow and the auto‑submit on 6‑digit input:
+  - Refreshed CSRF token before every `/api/totp_verify.php` call  
+  - Checked `response.ok` before parsing JSON  
+  - Improved `.catch` error handling
+
+- **verifyTOTP() endpoint enhancement**  
+  Inside the **pending‑login** branch of `verifyTOTP()`:
+  - Pulled `$_SESSION['pending_login_remember_me']`  
+  - If true, wrote the persistent token store, set `remember_me_token`, re‑issued the session cookie, and regenerated the session ID  
+  - Cleaned up pending session variables
+
+  ---
+
+## Changes 4/18/2025
+
+### fileListView.js
+
+- Seed and persist `itemsPerPage` from `localStorage`
+- Use `window.itemsPerPage` for pagination in gallery
+- Enable search input filtering in gallery mode
+- Always re‑render the view‑toggle button on gallery load
+- Restore per‑card action buttons (download, edit, rename, share)
+- Assign real `value` to checkboxes and call `updateFileActionButtons()` on change
+- Update `changePage` and `changeItemsPerPage` to respect `viewMode`
+
+### fileTags.js
+
+- Import `renderFileTable` and `renderGalleryView`
+- Re‑render the list after saving a single‑file tag
+- Re‑render the list after saving multi‑file tags
+
+---
+
+## Changes 4/17/2025
+
+- Generate OpenAPI spec and API HTML docs
+  - Fully auto‑generated OpenAPI spec (`openapi.json`) and interactive HTML docs (`api.html`) powered by Redoc.
+- .gitattributes added to mark (`openapi.json`) & (`api.html`) as documentation.
+- User Panel added API Docs link.
+- Adjusted remember_me_token.
+- Test pipeline
+
+---
+
+## Changes 4/16 Refactor API endpoints and modularize controllers and models
+
+- Reorganized project structure to separate API logic into dedicated controllers and models:
+  - Created adminController, userController, fileController, folderController, uploadController, and authController.
+  - Created corresponding models (AdminModel, UserModel, FileModel, FolderModel, UploadModel, AuthModel) for business logic.
+
+- Consolidated API endpoints under the /public/api folder with subfolders for admin, auth, file, folder, and upload endpoints.
+
+- Added inline OpenAPI annotations to document key endpoints (e.g., getConfig.php, updateConfig.php) for improved API documentation.
+
+- Updated configuration retrieval and update logic in AdminModel and AdminController to handle OIDC and login option booleans consistently, fixing issues with basic auth settings not updating on the login page.
+
+- Updated the client-side auth.js to correctly reference API endpoints (adjusted query selectors to reflect new document root) and load admin configuration from the updated API endpoints.
+
+- Minor improvements to CSRF token handling, error logging, and overall code readability.
+
+This refactor improves maintainability, testability, and documentation clarity across all API endpoints.
+
+### Refactor fixes and adjustments
+
+- Added fallback checks for disableFormLogin / disableBasicAuth / disableOIDCLogin when coming in either at the top level or under loginOptions.
+- Updated auth.js to read and store the nested loginOptions booleans correctly in localStorage, then show/hide the Basic‑Auth and OIDC buttons as configured.
+- Changed the logout controller to header("Location: /index.html?logout=1") so after /api/auth/logout.php it lands on the root index.html, not under /api/auth/.
+- Switched your share modal code to use a leading slash ("/api/file/share.php") so it generates absolute URLs instead of relative /share.php.
+- In the shared‑folder gallery, adjusted the client‑side image path to point at /uploads/... instead of /api/folder/uploads/...
+- Updated both AdminModel defaults and the AuthController to use the exact full path
+- Network Utilities Overhaul swapped out the old fetch wrapper for one that always reads the raw response, tries to JSON.parse it, and then either returns the parsed object on ok or throws it on error.
+- Adjusted your submitLogin .catch() to grab the thrown object (or string) and pass that through to showToast, so now “Invalid credentials” actually shows up.
+- Pulled the common session‑setup and “remember me” logic into two new helpers, finalizeLogin() (for AJAX/form/basic/TOTP) and finishBrowserLogin() (for OIDC redirects). That removed tons of duplication and ensures every path calls the same permission‑loading code.
+- Ensured that after you POST just a totp_code, we pick up pending_login_user/pending_login_secret, verify it, then immediately call finalizeLogin().
+- Expanded checkAuth.php Response now returns all three flags—folderOnly, readOnly, and disableUpload so client can handle every permission.
+- In auth.js’s updateAuthenticatedUI(), write all three flags into localStorage whenever you land on the app (OIDC, basic or form). That guarantees consistent behavior across page loads.
+- Made sure the OIDC handler reads the live config via AdminModel::getConfig() and pushes you through the TOTP flow if needed, then back to /index.html.
+- Dockerfile, custom-php.ini & start.sh moved into main repo for easier onboarding.
+- filerise-docker changed to dedicated CI/CD pipeline
+
+---
+
+## Changes 4/15/2025
+
+- Adjust Gallery View max columns based on screen size
+- Adjust headerTitle to update globally
+
+## Changes 4/14/2025
+
+- Fix Gallery View: medium screen devices get 3 max columns and small screen devices 2 max columns.
+- Ensure gallery view toggle button displays after refresh page.
+- Force resumable chunk size & fix chunk cleanup
+
+### filePreview.js Enhancements
+
+**Modal Layout Overhaul:**
+
+- **Left Panel:** Holds zoom in/out controls at the top and the "prev" button at the bottom.
+- **Center Panel:** Always centers the preview image.
+- **Right Panel:** Contains rotate left/right controls at the top and the "next" button at the bottom.
+
+**Consistent Control Presence:**
+
+- Both left and right panels are always included. When there’s only one image, placeholders are inserted in place of missing navigation buttons to ensure the image remains centered and that rotate controls are always visible.
+
+**Improved Transform Behavior:**
+
+- Transformation values (scale and rotation) are reset on each navigation event, ensuring predictable behavior and consistent presentation.
+
+---
+
+## Changes 4/13/2025 v1.1.3
+
+- Decreased header height some more and clickable logo.
+- authModals.js fully updated with i18n.js keys.
+- main.js added Dark & Light mode i18n.js keys.
+- New Admin section Header Settings to change Header Title.
+- Admin Panel confirm unsaved changes.
+- Added translations and data attributes for almost all user-facing text
+- Extend i18n support: Add new translation keys for Download and Share modals
+
+- **Slider Integration:**
+  - Added a slider UI (range input, label, and value display) directly above the gallery grid.
+  - The slider allows users to adjust the number of columns in the gallery from 1 to 6.
+- **Dynamic Grid Updates:**
+  - The gallery grid’s CSS is updated in real time via the slider’s value by setting the grid-template-columns property.
+  - As the slider value changes, the layout instantly reflects the new column count.
+- **Dynamic Image Resizing:**
+  - Introduced a helper function (getMaxImageHeight) that calculates the maximum image height based on the current column count.
+  - The max height of each image is updated immediately when the slider is adjusted to create a more dynamic display.
+- **Image Caching:**
+  - Implemented an image caching mechanism using a global window.imageCache object.
+  - Images are cached on load (via an onload event) to prevent unnecessary reloading, improving performance.
+- **Event Handling:**
+  - The slider’s event listener is set up to update both the gallery grid layout and the dimensions of the thumbnails dynamically.
+  - Share button event listeners remain attached for proper functionality across the updated gallery view.
+
+- **Input Validation & Security:**
+  - Used `filter_input()` to sanitize and validate incoming GET parameters (token, pass, page).
+  - Validated file system paths using `realpath()` and ensured the shared folder lies within `UPLOAD_DIR`.
+  - Escaped all dynamic outputs with `htmlspecialchars()` to prevent XSS.
+- **Share Link Verification:**
+  - Loaded and validated share records from the JSON file.
+  - Handled expiration and password protection (with proper HTTP status codes for errors).
+- **Pagination:**
+  - Implemented pagination by slicing the full file list into a limited number of files per page (default of 10).
+  - Calculated total pages and current page to create navigation links.
+- **View Toggle (List vs. Gallery):**
+  - Added a toggle button that switches between a traditional list view and a gallery view.
+  - Maintained two separate view containers (`#listViewContainer` and `#galleryViewContainer`) to support this switching.
+- **Gallery View with Image Caching:**
+  - For the gallery view, implemented a JavaScript function that creates a grid of image thumbnails.
+  - Each image uses a cache-busting query string on first load and caches its URL in a global `window.imageCache` for subsequent renders.
+- **Persistent Pagination Controls:**
+  - Moved the pagination controls outside the individual view containers so that they remain visible regardless of the selected view.
+
+---
+
+## Changes 4/12/2025
+
+- Moved Gallery view toggle button into header.
+- Removed css entries that are not needed anymore for Gallery View Toggle.
+- Change search box text when enabling advanced search.
+- Advanced/Basic search button as material icon on same row as search bar.
+
+### Advanced Search Implementation
+
+- **Advanced Search Toggle:**
+  - Added a global toggle (`window.advancedSearchEnabled`) and a UI button to switch between basic and advanced search modes.
+  - The toggle button label changes between "Advanced Search" and "Basic Search" to reflect the active mode.
+
+- **Fuse.js Integration Updates:**
+  - Modified the `searchFiles()` function to conditionally include the `"content"` key in the Fuse.js keys only when advanced search mode is enabled.
+  - Adjusted Fuse.js options by adding `ignoreLocation: true`, adjusting the `threshold`, and optionally assigning weights (e.g., a lower weight for `name` and a higher weight for `content`) to prioritize matches in file content.
+
+- **Backend (PHP) Enhancements:**
+  - Updated **getFileList.php** to read the content of text-based files (e.g., `.txt`, `.html`, `.md`, etc.) using `file_get_contents()`.
+  - Added a `"content"` property to the JSON response for eligible files to allow for full-text search in advanced mode.
+
+### Fuse.js Integration for Indexed Real-Time Searching**
+
+- **Added Fuse.js Library:** Included Fuse.js via a CDN `<script>` tag to leverage its client‑side fuzzy search capabilities.
+- **Created searchFiles Helper Function:** Introduced a new function that uses Fuse.js to build an index and perform fuzzy searches over file properties (file name, uploader, and nested tag names).
+- **Transformed JSON Object to Array:** Updated the loadFileList() function to convert the returned file data into an array (if it isn’t already) and assign file names from JSON keys.
+- **Updated Rendering Functions:** Modified both renderFileTable() and renderGalleryView() to use the searchFiles() helper instead of a simple in‑array .filter(). This ensures that every search—real‑time by user input—is powered by Fuse.js’s indexed search.
+- **Enhanced Search Configuration:** Configured Fuse.js to search across multiple keys (file name, uploader, and tags) so that users can find files based on any of these properties.
+
+---
+
+## Changes 4/11/2025
+
+- Fixed fileDragDrop issue from previous update.
+- Fixed User Panel height changing unexpectedly on mouse over.
+- Improved JS file comments for better documentation.
+- Fixed userPermissions not updating after initial setting.
+- Disabled folder and file sharing for readOnly users.
+- Moved change password close button to the top right of the modal.
+- Updated upload regex pattern to be Unicode‑enabled and added additional security measures. [(#19)](https://github.com/error311/FileRise/issues/19)
+- Updated filename, folder, and username regex acceptance patterns.
+- Updated robthree/twofactorauth to v3 and endroid/qr-code to v5
+- Updated TOTP integration (namespace, enum, QR provider) accordingly
+- Updated docker image from 22.04 to 24.04 <https://github.com/error311/filerise-docker>
+- Ensure consistent session behavior
+- Fix totp_setup.php to use header-based CSRF token verification
+
+---
+
+## Shift Key Multi‑Selection Changes 4/10/2025 v1.1.1
+
+- **Implemented Range Selection:**
+  - Modified the `toggleRowSelection` function so that when the Shift key is held down, all rows between the last clicked (anchor) row (stored as `window.lastSelectedFileRow`) and the currently clicked row are selected.
+- **Modifier Handling:**
+  - Regular clicks (or Ctrl/Cmd clicks) simply toggle the clicked row without clearing other selections.
+- **Prevented Default Browser Behavior:**
+  - Added `event.preventDefault()` in the Shift‑click branch to avoid unwanted text selection.
+- **Maintaining the Anchor:**
+  - The last clicked row is stored for future range selections.
+
+## Total Files and File Size Summary
+
+- **Size Calculation:**
+  - Created `parseSizeToBytes(sizeStr)` to convert file size strings (e.g. `"456.9KB"`, `"1.2 MB"`) into a numerical byte value.
+  - Created `formatSize(totalBytes)` to format a byte value into a human‑readable string (choosing between Bytes, KB, MB, or GB).
+  - Created `buildFolderSummary(filteredFiles)` to:
+    - Sum the sizes of all files (using `parseSizeToBytes`).
+    - Count the total number of files.
+- **Dynamic Display in `loadFileList`:**
+  - Updated `loadFileList` to update a summary element (with `id="fileSummary"`) inside the `#fileListActions` container when files are present.
+  - When no files are found, the summary element is hidden (setting its `display` to `"none"` or clearing the container).
+- **Responsive Styling:**
+  - Added CSS media queries to the `#fileSummary` element so that on small screens it is centered and any extra side margins are removed. Dark and light mode supported.
+
+- **Other changes**
+
+  - `shareFolder.php` updated to display format size.
+  - Fix to prevent the filename text from overflowing its container in the gallery view.
+  - Reduced header height.
+  - Create Folder changed to Material Icon `create_new_folder`
+
+---
+
+## Folder Sharing Feature - Changelog 4/9/2025 v1.1.0
+
+### New Endpoints
+
+- **createFolderShareLink.php:**  
+  - Generates secure, expiring share tokens for folders (with an optional password and allow-upload flag).  
+  - Stores folder share records separately from file shares in `share_folder_links.json`.  
+  - Builds share links that point to **shareFolder.php**, using a proper BASE_URL or the server’s IP when a default placeholder is detected.
+
+- **shareFolder.php:**  
+  - Serves shared folders via GET requests by reading tokens from `share_folder_links.json`.
+  - Validates token expiration and password (if set).
+  - Displays folder contents with pagination (10 items per page) and shows file sizes in megabytes.
+  - Provides navigation links (Prev, Next, and numbered pages) for folder listings.
+  - Includes an upload form (if allowed) that redirects back to the same share page after upload.
+  
+- **downloadSharedFile.php:**  
+  - A dedicated, secure download endpoint for shared files.
+  - Validates the share token and ensures the requested file is inside the shared folder.
+  - Serves files using proper MIME types and Content-Disposition headers (inline for images, attachment for others).
+
+- **uploadToSharedFolder.php:**  
+  - Handles file uploads for public folder shares.
+  - Enforces file size limits and file type whitelists.
+  - Generates unique filenames (with a unique prefix) to prevent collisions.
+  - Updates metadata for the uploaded file (upload date and sets uploader as "Outside Share").
+  - Redirects back to **shareFolder.php** after a successful upload so the file listing refreshes.
+
+### New Front-End Module
+
+- **folderShareModal.js:**  
+  - Provides a modal interface for users to generate folder share links.
+  - Includes expiration selection, optional password entry, and an allow-upload checkbox.
+  - Uses the **createFolderShareLink.php** endpoint to generate share links.
+  - Displays the generated share link with a “copy to clipboard” button.
+
+---
+
+## Changes 4/8/2025
+
+**May have missed some stuff or could have bugs. Please report any issue you may encounter.**
+
+- **i18n Integration:**
+  - Implemented a semi-complete internationalization (i18n) system for all user-facing texts in FileRise.
+  - Created an `i18n.js` module containing a translations object with full keys for English (en), Spanish (es), and French (fr).
+  - Updated JavaScript code to replace hard-coded strings with the `t()` translation function.
+  - Enhanced HTML and modal templates to support dynamic language translations using data attributes (data-i18n-key, data-i18n-placeholder, etc.).
+
+- **Language Dropdown & Persistence:**
+  - Added a language dropdown to the user panel modal allowing users to select their preferred language.
+  - Persisted the selected language in localStorage, ensuring that the preferred language is automatically applied on page refresh.
+  - Updated main.js to load and set the user’s language preference on DOMContentLoaded by calling `setLocale()` and `applyTranslations()`.
+
+- **Bug Fixes & Improvements:**
+  - Fixed issues with evaluation of translation function calls in template literals (ensured proper syntax with `${t("key")}`).
+  - Updated the t() function to be more defensive against missing keys.
+  - Provided instructions and code examples to ensure the language change settings are reliably saved and applied across sessions.
+
+- **ZIP Download Flow**
+  - Progress Modal: In the ZIP download handler (confirmDownloadZip), added code to show a progress modal (with a spinning icon) as soon as the user confirms the download and before the request to create the ZIP begins. Once the blob is received or an error occurs, we hide the progress modal.
+  - Inline Handlers and Global Exposure: Ensured that functions like confirmDownloadZip are attached to the global window object (or called via appropriate inline handlers) so that the inline onclick events in the HTML work without reference errors.
+
+- **Single File Download Flow**
+  - Modal Popup for Single File: Replaced the direct download link for single files with a modal-driven flow. When the download button is clicked, the openDownloadModal(fileName, folder) function is called. This stores the file details and shows a modal where the user can confirm (or edit) the file name.
+  - Confirm Download Function: When the user clicks the Download button in the modal, the confirmSingleDownload() function is called. This function constructs a URL for download.php (using GET parameters for folder and file), fetches the file as a blob, and triggers a download using a temporary anchor element. A progress modal is also used here to give feedback during the download process.
+
+- **Zip Extraction**
+  - Reused Zip Download modal to use same progress Modal Popup with Extracting files.... text.
+

+
+## Changes 4/7/2025 v1.0.9
+
+- TOTP one time recovery code added
+- fix(security): mitigate CodeQL alerts by adding SRI attributes and sanitizing DOM content
+
+---
+
+## Changes 4/6/2025 v1.0.8
+
+**May need to log out and log back in if using remember me**  
+
+Changelog: Modularize fileManager.js
+
+1. **fileListView.js**  
+ • Extracted all table/gallery rendering logic (loadFileList, renderFileTable, renderGalleryView, sortFiles, date parsing, pagination).  
+ • Kept global helpers on window (changePage, changeItemsPerPage).  
+ • Added explicit re‑binding of context‑menu and drag‑drop handlers after each render.  
+2. **filePreview.js**  
+ • Moved “Preview” and “Share” modal code here (previewFile, openShareModal, plus displayFilePreview helper).  
+ • Exposed window.previewFile for inline onclick compatibility.  
+3. **fileEditor.js**  
+ • Isolated CodeMirror editor logic (editFile, saveFile, sizing, theme toggles).  
+ • Exported utility functions (getModeForFile, adjustEditorSize, observeModalResize).  
+4. **fileDragDrop.js**  
+ • Encapsulated all drag‑start and folder drag/drop handlers (fileDragStartHandler, folderDragOverHandler, etc.).  
+5. **fileMenu.js** (formerly contextMenu.js)  
+ • Centralized right‑click context menu construction and binding (showFileContextMenu, fileListContextMenuHandler, bindFileListContextMenu).  
+ • Now calls the correct single vs. multi‑tag modals.  
+6. **fileActions.js**  
+ • Consolidated all “Delete”, “Copy”, “Move”, “Download Zip”, “Extract Zip”, “Rename” workflows and their modals.  
+ • Exposed initFileActions() to wire up toolbar buttons on page load.  
+7. **fileManager.js** (entry point)  
+ • Imports all the above modules.  
+ • On DOM ready: calls initFileActions(), attaches folder tree drag/drop, and global key handlers.
+
+Changelog: OIDC, Basic Auth & TOTP Integration
+
+1. **auth.php (OIDC)**  
+ • Detects callback via `?code` or `?oidc=callback`.  
+ • Checks for a TOTP secret after OIDC auth, stores pending login in session, redirects with `?totp_required=1`.  
+ • Finalizes session only after successful TOTP verification.  
+
+2. **login_basic.php (Basic Auth)**  
+ • After password verification, checks for TOTP secret.  
+ • Stores pending login & secret in session, redirects to TOTP modal.  
+ • Completes session setup only after TOTP verification.  
+
+3. **authModals.js & auth.js**  
+ • Detect `?totp_required=1` and open the TOTP modal.  
+ • Override `showToast` to suppress “Please log in…” during TOTP.  
+ • Wrap `openTOTPLoginModal` to disable Basic/OIDC buttons (but keep form-login visible).  
+ • On invalid TOTP code, keep modal open, clear input, and refocus for retry.  
+
+4. **totp_verify.php**  
+ • Consolidates login and setup TOTP flows in one endpoint.  
+ • Enforces CSRF token and authentication guard.  
+ • Verifies TOTP, regenerates session on success, and clears pending state.  
+ • Production‑hardened: secure cookies, CSP header, rate‑limiting (5 attempts), standardized JSON responses, and robust error handling.

+
+Change Log for dragAndDrop.js Enhancements
+
+- **Header Drop Zone Integration:**
+  - Added a new header drop zone (`#headerDropArea`) to support dragging cards (Upload and Folder Management) into the header.
+  - Created functionality to display a compact Material icon in the header when a card is dropped there.
+
+- **Modal Popup for Header Cards:**
+  - Implemented a modal overlay that displays the full card when the user hovers or clicks the header icon.
+  - Added toggle functionality so that the modal can be locked open or auto-hide based on mouse interactions.
+
+- **State Preservation via Hidden Container:**
+  - Introduced a hidden container (`#hiddenCardsContainer`) to preserve the original state of the Upload and Folder Management cards.
+  - Modified logic so that instead of removing these cards from the DOM when dropped into the header, they are moved to the hidden container.
+  - Updated modal show/hide functions to move the card from the hidden container into the modal (and back), ensuring interactive elements (e.g., folder tree, file selection) remain fully initialized and retain their state across page refreshes.
+
+- **Local Storage Integration for Header Order:**
+  - Added `saveHeaderOrder()` and `loadHeaderOrder()` functions to persist the header drop zone order.
+  - Integrated header order saving/updating with drag-and-drop events so that header placements are maintained after refresh.
+
+- **General Drag & Drop Enhancements:**
+  - Maintained smooth drag-and-drop animations and reflow for all drop zones (sidebar, top, and header).
+  - Ensured existing functionalities (like file uploads and folder tree interactions) work seamlessly alongside the new header drop zone.
+  
+## Brief Description
+
+The enhancements extend the existing drag-and-drop functionality by adding a header drop zone where cards are represented by a compact Material icon. To preserve interactive state (such as the folder tree’s current folder or file input functionality) across page refreshes, the original cards are never fully removed from the DOM. Instead, they are moved into a hidden container, and when a user interacts with the header icon, the card is temporarily transferred into a modal overlay for full interaction. When the modal is closed, the card is returned to the hidden container, ensuring that its state remains intact. Additionally, header order is saved to local storage so that user-customized layouts persist across sessions.

+
+## changes 3/29/2025
+
+**Frontend (JavaScript)**  
+
+**File:** `auth.js`
+
+- **Added OIDC Login Flow**
+  - Created a dedicated OIDC login button (`oidcLoginBtn`).
+  - Redirects users to OIDC authentication via `auth.php?oidc`.

+
+⸻
+
+**Backend (PHP)**  
+
+**File:** `auth.php`
+
+- **OIDC Authentication**
+  - Integrated Jumbojett’s OpenID Connect client to handle OIDC flows.
+  - Reads OIDC configuration from an encrypted JSON file (`adminConfig.json`).
+  - Redirects users to OIDC provider and handles callbacks properly, authenticating users and initiating PHP sessions.
+
+- **Security Enhancements**
+  - Implemented robust error handling for authentication failures.
+  - Session regeneration after successful login to mitigate session fixation risks.
+
+**Configuration Handling**  
+
+**File:** `getConfig.php`
+
+- **Secure Configuration Retrieval**
+  - Retrieves encrypted OIDC configuration from disk.
+  - Decrypts and sends JSON configuration securely to the frontend.
+  - Defaults provided if configuration does not exist.
+
+**File:** `updateConfig.php`
+
+- **Secure Configuration Updates**
+  - Strictly checks for authenticated admin sessions and validates CSRF tokens.
+  - Validates and sanitizes user input thoroughly (OIDC URL, client ID, secret, redirect URI).
+  - Updates encrypted configuration file securely, ensuring atomic writes (`LOCK_EX`).
+
+- **Consistent Styling**
+  - Modal dynamically adjusts styling based on dark/light modes.
+  - Improved accessibility with clear icons, visual hierarchy, and structured form fields.
+
+- **Enhanced Feedback**

+
+---
+
+## changes 3/25/2025
+
+- **Context Menu Enhancements:**
+  - **Right‑Click Context Menu:**
+    - Added context menu support for file list rows so that right‑clicking shows a custom menu.
+    - When multiple files are selected, options like “Delete Selected”, “Copy Selected”, “Move Selected”, “Download Zip” are shown.
+    - When a file with a “.zip” extension is among the selections, an “Extract Zip” option is added.
+  - **Single File Options:**
+    - For a single selected file, additional items (“Preview”, “Edit”, and “Rename”) are appended.
+    - The “Edit” option appears only if `canEditFile(file.name)` returns true.
+- **Keyboard Shortcuts:**
+  - **Delete Key Shortcut:**
+    - Added a global keydown listener to detect the Delete (or Backspace on Mac) key.
+    - When pressed (and if no input/textarea is focused) with files selected, it triggers `handleDeleteSelected()` to open the delete confirmation modal.
+- **Modals & Enter-Key Handling:**
+  - **attachEnterKeyListener Update:**
+    - Modified the function to use the “keydown” event (instead of “keypress”) for better reliability.
+    - Ensured the modal is made focusable (by setting a `tabindex="-1"`) and focused immediately after being displayed.
+    - This update was applied to modals for rename, download zip, and delete operations.
+  - **Delete Modal Specific:**
+    - It was necessary to call `attachEnterKeyListener` for the delete modal after setting its display to “block” to ensure it captures the Enter key.
+- **File Editing Adjustments:**
+  - **Content-Length Check:**
+    - Modified the `editFile` function so that it only blocks files when the Content-Length header is non‑null and greater than 10 MB.
+    - This change allows editing of 0 KB files (or files with Content-Length “0”) without triggering the “File too large” error.
+
+- **Context Menu for Folder Manager:**
+  - Provided a separate implementation for a custom context menu for folder manager elements.
+  - Bound the context menu to both folder tree nodes (`.folder-option`) and breadcrumb links (`.breadcrumb-link`) so that right‑clicking on either triggers a custom menu.
+  - The custom menu for folders includes actions for “Create Folder”, “Rename Folder”, and “Delete Folder.”
+  - Added guidance to ensure that breadcrumb HTML elements contain the appropriate class and `data-folder` attribute.
+- **Keyboard Shortcut for Folder Deletion (Suggestion):**
+  - Suggested adding a global keydown listener in `folderManager.js` to trigger folder deletion (via `openDeleteFolderModal()`) when Delete/Backspace is pressed and a folder other than “root” is selected.
+
+- **Event Listener Timing:**
+  - Ensured that context menu and key event listeners are attached after the corresponding DOM elements are rendered.
+  - Added explicit focus calls (and `tabindex` attributes) for modals to capture keyboard events.
+
+---
+
+## changes 3/24/2025
+
+### config.php
+
+- **Encryption Functions Added:**
+  - Introduced `encryptData()` and `decryptData()` functions using AES‑256‑CBC to encrypt and decrypt persistent tokens.
+- **Encryption Key Handling:**
+  - Added code to load the encryption key from an environment variable (`PERSISTENT_TOKENS_KEY`) with a fallback default.
+- **Persistent Token Auto-Login:**
+  - Modified the auto-login logic to check for a `remember_me_token` cookie.
+  - If the persistent tokens file exists, it now reads and decrypts its content before decoding JSON.
+  - If a token is expired, the code removes the token, re-encrypts the updated array, writes it back to disk, and clears the cookie.
+- **Cookie and Session Settings:**
+  - No major changes aside from integrating the encryption functionality into the token handling.
+
+### auth.php
+
+- **Login Process and “Remember Me” Functionality:**
+  - When “Remember me” is checked, generates a secure random token.
+  - Loads the persistent tokens file (if it exists), decrypts its content, and decodes the JSON.
+  - Inserts the new token (with associated username and expiry) into the persistent tokens array.
+  - Encrypts the updated tokens array and writes it back to the file.
+  - Sets the `remember_me_token` cookie using the `$secure` flag and expiry.
+- **Authentication & Brute Force Protection:**
+  - The authentication logic and brute-force protection remain largely unchanged.
+
+### logout.php
+
+- **Persistent Token Removal:**
+  - If a `remember_me_token` cookie exists, the script loads the persistent tokens file, decrypts its content, removes the token if present, re-encrypts the array, and writes it back.
+- **Cookie Clearance and Session Destruction:**
+  - Clears the `remember_me_token` cookie.
+  - Destroys session data as before.
+
+### networkUtils.js
+
+- **Fetch Wrapper Enhancements:**
+  - Modified `sendRequest()` to clone the response before attempting to parse JSON.
+  - If JSON parsing fails (e.g., because of unexpected response content), the cloned response is used to read the text, preventing the “Body is disturbed or locked” error.
+- **Error Handling Improvements:**
+  - Improved error handling by ensuring the response body is read only once.
+
+---
+
+## changes 3/23/2025 v1.0.1
+
+- **Resumable File Upload Integration and Folder Support**
+  - **Legacy Drag-and-Drop Folder Uploads:**
+    - Supports both file and folder uploads via drag-and-drop.
+    - Recursively traverses dropped folders to extract files.
+    - Uses original XHR-based upload code for folder uploads so that files are placed in the correct folder (i.e. based on the current folder in the app’s folder tree).
+  - **Resumable.js for File Picker Uploads:**
+    - Integrates Resumable.js for file uploads via the file picker.
+    - Provides pause, resume, and retry functionality:
+    - Pause/Resume: A pause/resume button is added for each file selected via the file picker. When the user clicks pause, the file upload pauses and the button switches to a “play” icon. When the user clicks it again, the system triggers a resume sequence (calling the upload function twice to ensure proper restart).
+    - Retry: If a file upload encounters an error, the pause/resume button changes to a “replay” icon, allowing the user to retry the upload.
+    - During upload, the UI displays the progress percentage along with the calculated speed (bytes/KB/MB per second).
+    - Files are previewed using material icons for non-image files and actual image previews for image files (using a helper function that creates an object URL for image files).
+  - **Temporary Chunk Folder Removal:**
+    - When a user cancels an upload via the remove button (X), a POST request is sent to a PHP endpoint (removeChunks.php) that:
+    - Validates the CSRF token.
+    - Recursively deletes the temporary folder (which stores file chunks) from the uploads directory.
+  - **Additional Details:**
+    - The file list UI remains visible (instead of auto-disappearing after 5 seconds) if there are any files still present or errors, ensuring that users can retry failed uploads.
+    - The system uses a chunk size of 3MB and supports multiple simultaneous uploads.
+    - All endpoints include CSRF protection and input validation to ensure secure operations.
+

+
+## changes 3/21/2025 v1.0.0
+
+- **Trash Feature Implementation**
+  - Added functionality to move deleted files to a Trash folder.
+  - Implemented trash metadata storage (trash.json) capturing original folder, file name, trashed timestamp, uploader, and deletedBy.
+  - Developed restore feature allowing admins to restore individual or all files from Trash.
+  - Developed delete feature allowing permanent deletion (Delete Selected and Delete All) from Trash.
+  - Implemented auto-purge of trash items older than 3 days.
+  - Updated trash modal design for better user experience.
+  - Incorporated material icons with tooltips in restore/delete buttons.
+  - Improved responsiveness of the trash modal with a centered layout and updated CSS.
+  - Fixed issues where trashed files with missing metadata were not restored properly.
+  - Resolved problems with the auto-purge mechanism when trash.json was empty or contained unexpected data.
+  - Adjusted admin button logic to correctly display the restore button for administrators.
+  - Improved error handling on restore and delete actions to provide more informative messages to users.
+- **Other changes**
+  - CSS adjusted (this needs to be refactored)
+  - Fixed setup mode CSRF issue in addUser.php
+  - Adjusted modals buttons in index.html & folderManager.js
+  - Changed upload.php safe pattern
+  - Hide trash folder
+  - Reworked auth.js
+
+---
+
+## changes 3/20/2025
+
+- **Drag & Drop Feature**
+  - For a single file: shows a file icon alongside the file name.
+  - For multiple files: shows a file icon and a count of files.
+  - Styling Adjustments:
+  - Modified drag image styling (using inline-flex, auto width, and appropriate padding) so that the drag image only sizes to its content and does not extend off the screen.
+  - Revised the folder drop handler so that it reads the array of file names from the drag data and sends that array (instead of a single file name) to the server (moveFiles.php) for processing.
+  - Attached dragover, dragleave, and drop event listeners to folder tree nodes (the elements with the class folder-option) to enable a drop target.
+  - Added a global dragover event listener (in main.js) that auto-scrolls the page when the mouse is near the top or bottom of the viewport during a drag operation. This ensures you can reach the folder tree even if you’re far down the file list.
+
+---
+
+## changes 3/19/2025
+
+## Session & Security Enhancements
+
+- **Secure Session Cookies:**  
+  - Configured session cookies with a 2-hour lifetime, HTTPOnly, and SameSite settings.
+  - Regenerating the session ID upon login to mitigate session fixation.
+- **CSRF Protection:**  
+  - Ensured the CSRF token is generated in `config.php` and returned via a `token.php` endpoint.
+  - Updated front-end code (e.g. in `main.js`) to fetch the CSRF token and update meta tags.
+- **Session Expiration Handling:**  
+  - Updated the `loadFileList` and other functions to check for HTTP 401 responses and trigger a logout or redirect if the session has expired.
+
+## File Management Improvements
+
+### Unique Naming to Prevent Overwrites
+
+- **Copy & Move Operations:**  
+  - Added a helper function `getUniqueFileName()` to both `copyFiles.php` and `moveFiles.php` that checks for duplicates and appends a counter (e.g., “ (1)”) until a unique filename is determined.
+  - Updated metadata handling so that when a file is copied/moved and renamed, the corresponding metadata JSON (per-folder) is updated using the new unique filename.
+- **Rename Functionality:**  
+  - Updated `renameFile.php` to:
+    - Allow filenames with parentheses by updating the regex.
+    - Check if a file with the new name already exists.
+    - Generate a unique name using similar logic if needed.
+    - Update folder-specific metadata accordingly.
+
+### Metadata Management
+
+- **Per-Folder Metadata Files:**  
+  - Changed metadata storage so that each folder uses its own metadata file (e.g., `root_metadata.json` for the root folder and `FolderName_metadata.json` for subfolders).
+  - Updated metadata file path generation functions to replace slashes, backslashes, and spaces with dashes.
+
+## Gallery / Grid View Enhancements
+
+- **Gallery (Grid) View:**  
+  - Added a toggle option to switch between a traditional table view and a gallery view.
+  - The gallery view arranges image thumbnails in a grid layout with configurable column options (e.g., 3, 4, or 5 columns).
+  - Under each thumbnail, action buttons (Download, Edit, Rename, Share) are displayed for quick access.
+- **Preview Modal Enhancements:**  
+  - Updated the image preview modal to include navigation buttons (prev/next) for browsing through images.
+  - Improved scaling and styling of preview modals for a better user experience.
+
+## Share Link Functionality
+
+- **Share Link Generation (createShareLink.php):**  
+  - Generate shareable links for files with:
+    - A secure token.
+    - Configurable expiration times (including options for 30, 60, 120, 180, 240 minutes, and a 1-day option).
+    - Optional password protection (passwords are hashed).
+  - Store share links in a JSON file (`share_links.json`) with details (folder, file, expiration timestamp, hashed password).
+- **Share Endpoint (share.php):**  
+  - Validate tokens, expiration, and passwords.
+  - Serve files inline for images or force download for other file types.
+  - Share URL is configurable via environment variables or auto-detected from the server.
+- **Front-End Configuration:**  
+  - Created a `token.php` endpoint that returns CSRF token and SHARE_URL.
+  - Updated the front-end (in `main.js`) to fetch configuration data and update meta tags for CSRF and share URL, allowing index.html to remain static.
+
+## Apache & .htaccess / Server Security
+
+- **Disable Directory Listing:**  
+  - Recommended adding an .htaccess file (e.g., in `uploads/`) with `Options -Indexes` to disable directory indexing.
+- **Restrict Direct File Access:**  
+  - Protected sensitive files (e.g., users.txt) via .htaccess.
+  - Filtered out hidden files (files beginning with a dot) from the file list in `getFileList.php`.
+- **Proxy Download:**  
+  - A proxy download mechanism has been implemented (via endpoints like `download.php` and `downloadZip.php`) so that every file download request goes through a PHP script. This script validates the session and CSRF token before streaming the file, ensuring that even if a file URL is guessed, only authenticated users can access it.
+
+---
+
+## changes 3/18/2025
+
+- **CSRF Protection:** All state-changing endpoints (such as those for folder and file operations) include CSRF token validation to ensure that only legitimate requests from authenticated users are processed.

+
+## changes 3/10/2025
+
+- File Editing Enhancements:
+  - Integrated CodeMirror into the file editor modal for syntax highlighting, line numbers, and adjustable font size.
+  - Added zoom in/out controls (“A-” / “A+”) in the editor modal to let users adjust the text size and number of visible lines.
+  - Updated the save function to retrieve edited content from the CodeMirror instance (using editor.getValue()) instead of the underlying textarea.
+- Image Preview Improvements:
+  - Added a new “Preview” button (with a Material icon) in the Actions column for image files.
+  - Implemented an image preview modal that centers content using flexbox, scales images using object-fit: contain, and maintains the original aspect ratio.
+  - Fixed URL encoding for subfolder paths so that images in subfolders (e.g. NewFolder2/Vita) load correctly without encoding slashes.
+- Download ZIP Modal Updates:
+  - Replaced the prompt-based download ZIP with a modal dialog that allows users to enter a custom name for the ZIP file.
+  - Updated the modal logic to ensure proper flow (cancel/confirm) and pass the custom filename to the download process.
+- Folder URL Handling:
+  - Modified the folder path construction in the file list rendering to split folder names into segments and encode each segment individually. This prevents encoding of slashes, ensuring correct URLs for files in subfolders.
+- General UI & Functionality:
+  - Ensured that all global functions (e.g., toggleRowSelection, updateRowHighlight, and sortFiles) are declared and attached to window so that inline event handlers can access them.
+  - Maintained responsive design, preserving existing features such as pagination, sorting, batch operations (delete, copy, move), and folder management.

+  - Split the original `utils.js` into multiple ES6 modules for network requests, DOM utilities, file management, folder management, uploads, and authentication.
+  - Converted all code to ES6 modules with `import`/`export` syntax and exposed necessary functions globally.
+- **File List Rendering & Pagination:**
+  - Implemented pagination in `fileManager.js` to allow displaying 10, 20, 50, or 100 items per page.
+  - Added global functions (`changePage` and `changeItemsPerPage`) for pagination control.
+  - Added a pagination control section below the file list table.
+- **Date Sorting Enhancements:**
+  - Created a custom date parser (`parseCustomDate`) to convert date strings.
+  - Adjusted the parser to handle two-digit years by adding 2000.
+  - Integrated the parser into the sorting function to reliably sort “Date Modified” and “Upload Date” columns.
+- **File Upload Improvements:**
+  - Enabled multi-file uploads with individual progress tracking (visible for the first 10 files).
+  - Ensured that the file list refreshes immediately after uploads complete.
+  - Kept the upload progress list visible for a configurable delay to allow users to verify upload success.
+  - Reattached event listeners after the file list is re-rendered.
+- **File Action Buttons:**
+  - Unified button state management so that Delete, Copy, and Move buttons remain visible as long as files exist, and are only enabled when files are selected.
+  - Modified the logic in `updateFileActionButtons` and removed conflicting code from `initFileActions`.
+  - Ensured that the folder dropdown for copy/move is hidden when no files exist.
+- **Rename Functionality:**
+  - Added a “Rename” button to the Actions column for every file.
+  - Implemented a `renameFile` function that prompts for a new name, calls a backend script (`renameFile.php`) to perform the rename, updates metadata, and refreshes the file list.
+- **Responsive & UI Tweaks:**
+  - Applied CSS media queries to hide secondary columns on small screens.
+  - Adjusted file preview and icon styling for better alignment.
+  - Centered the header and optimized the layout for a clean, modern appearance.
+  
+*This changelog and feature summary reflect the improvements made during the refactor from a monolithic utils file to modular ES6 components, along with enhancements in UI responsiveness, sorting, file uploads, and file management operations.*

+
+## Adding New Language Translations
+
+FileRise supports internationalization (i18n) and localization via a central translation file (`i18n.js`). If you would like to contribute a new language translation, please follow these steps:
+
+1. **Update `i18n.js`:**  
+   Open the `i18n.js` file located in the `js` directory. Within the `translations` object, add a new property using the appropriate [ISO language code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) as the key. Copy the structure from an existing language block and translate each key.
+
+   **Example (for German):**
+
+   ```js
+   de: {
+     "please_log_in_to_continue": "Bitte melden Sie sich an, um fortzufahren.",
+     "no_files_selected": "Keine Dateien ausgewählt.",

-## Features
+## Features at a Glance or [Full Features Wiki](https://github.com/error311/FileRise/wiki/Features)
 
-- **Multiple File/Folder Uploads with Progress (Resumable.js Integration):**
-  - Users can effortlessly upload multiple files and folders simultaneously by either selecting them through the file picker or dragging and dropping them directly into the interface.
-  - **Chunked Uploads:** Files are uploaded in configurable chunks (default set as 3 MB) to efficiently handle large files.
-  - **Pause, Resume, and Retry:** Uploads can be paused and resumed at any time, with support for retrying failed chunks.
-  - **Real-Time Progress:** Each file shows an individual progress bar that displays percentage complete and upload speed.
-  - **File & Folder Grouping:** When many files are dropped, files are automatically grouped into a scrollable wrapper, ensuring the interface remains clean.
-  - **Secure Uploads:** All uploads integrate CSRF token validation and other security checks.
+- 🚀 **Easy File Uploads:** Upload multiple files and folders via drag & drop or file picker. Supports large files with pause/resumable chunked uploads and shows real-time progress for each file. No more failed transfers – FileRise will pick up where it left off if your connection drops.
 
-- **Built-in File Editing & Renaming:**
-  - Text-based files (e.g., .txt, .html, .js) can be opened and edited in a modal window using CodeMirror for:
-    - Syntax highlighting
-    - Line numbering
-    - Adjustable font sizes
-  - Files can be renamed directly through the interface.
-  - The renaming functionality now supports names with parentheses and checks for duplicate names, automatically generating a unique name (e.g., appending “ (1)”) when needed.
-  - Folder-specific metadata is updated accordingly.
-  - **Enhanced File Editing Check:** Files with a Content-Length of 0 KB are now allowed to be edited.
+- 🗂️ **File Management:** Full set of file/folder operations – move or copy files (via intuitive drag-drop or dialogs), rename items, and delete in batches. You can even download selected files as a ZIP archive or extract uploaded ZIP files server-side. Organize content with an interactive folder tree and breadcrumb navigation for quick jumps.
 
-- **Built-in File Preview:**
-  - Users can quickly preview images, videos, and PDFs directly in modal popups without leaving the page.
-  - The preview modal supports inline display of images (with proper scaling) and videos with playback controls.
-  - Navigation (prev/next) within image previews is supported for a seamless browsing experience.
+- 🗃️ **Folder Sharing & File Sharing:** Easily share entire folders via secure, expiring public links. Folder shares can be password-protected, and shared folders support file uploads from outside users with a separate, secure upload mechanism. Folder listings are paginated (10 items per page) with navigation controls, and file sizes are displayed in MB for clarity. Share files with others using one-time or expiring public links (with password protection if desired) – convenient for sending individual files without exposing the whole app.
 
-- **Gallery (Grid) View:**
-  - In addition to the traditional table view, users can toggle to a gallery view that arranges image thumbnails in a grid layout.
-  - The gallery view offers multiple column options (e.g., 3, 4, or 5 columns) so that users can choose the layout that best fits their screen.
-  - Action buttons (Download, Edit, Rename, Share) appear beneath each thumbnail for quick access.
+- 📚 **API Documentation:** Fully auto‑generated OpenAPI spec (`openapi.json`) and interactive HTML docs (`api.html`) powered by Redoc.
 
-- **Batch Operations (Delete/Copy/Move/Download/Extract Zip):**
-  - **Delete Files:** Delete multiple files at once.
-  - **Copy Files:** Copy selected files to another folder with a unique-naming feature to prevent overwrites.
-  - **Move Files:** Move selected files to a different folder, automatically generating a unique filename if needed to avoid data loss.
-  - **Download Files as ZIP:** Download selected files as a ZIP archive. Users can specify a custom name for the ZIP file via a modal dialog.
-  - **Extract Zip:** When one or more ZIP files are selected, users can extract the archive(s) directly into the current folder.
-  - **Drag & Drop:** Easily move files by selecting them from the file list and simply dragging them onto your desired folder in the folder tree or breadcrumb. When you drop the files onto a folder, the system automatically moves them, updating your file organization in one seamless action.
-  - **Enhanced Context Menu & Keyboard Shortcuts:**
-    - **Right-Click Context Menu:**  
-      - A custom context menu appears on right-clicking within the file list.  
-      - For multiple selections, options include Delete Selected, Copy Selected, Move Selected, Download Zip, and (if applicable) Extract Zip.  
-      - When exactly one file is selected, additional options (Preview, Edit [if editable], and Rename) are available.
-    - **Keyboard Shortcut for Deletion:**  
-      - A global keydown listener detects Delete/Backspace key presses (when no input is focused) to trigger the delete operation.
+- 📝 **Built-in Editor & Preview:** View images, videos, audio, and PDFs inline with a preview modal – no need to download just to see them. Edit text/code files right in your browser with a CodeMirror-based editor featuring syntax highlighting and line numbers. Great for config files or notes – tweak and save changes without leaving FileRise.
 
-- **Folder Management:**
-  - Organize files into folders and subfolders with the ability to create, rename, and delete folders.
-  - A dynamic folder tree in the UI allows users to navigate directories easily, and any changes are immediately reflected in real time.
-  - **Per-Folder Metadata Storage:** Each folder has its own metadata JSON file (e.g., `root_metadata.json`, `FolderName_metadata.json`), and operations (copy/move/rename) update these metadata files accordingly.
-  - **Intuitive Breadcrumb Navigation:** Clickable breadcrumbs enable users to quickly jump to any parent folder, streamlining navigation across subfolders. Supports drag & drop to move files.
-  - **Folder Manager Context Menu:**  
-    - Right-clicking on a folder (in the folder tree or breadcrumb) brings up a custom context menu with options for creating, renaming, and deleting folders.
-  - **Keyboard Shortcut for Folder Deletion:**  
-    - A global key listener (Delete/Backspace) is provided to trigger folder deletion (with safeguards to prevent deleting the root folder).
+- 🏷️ **Tags & Search:** Categorize your files with color-coded tags and locate them instantly using our indexed real-time search. Easily switch to Advanced Search mode to enable fuzzy matching not only across file names, tags, and uploader fields but also within the content of text files—helping you find that “important” document even if you make a typo or need to search deep within the file.
 
-- **Sorting & Pagination:**
-  - The file list can be sorted by name, modified date, upload date, file size, or uploader.
-  - Pagination controls let users navigate through files with selectable page sizes (10, 20, 50, or 100 items per page) and “Prev”/“Next” navigation buttons.
+- 🔒 **User Authentication & User Permissions:** Secure your portal with username/password login. Supports multiple users – create user accounts (admin UI provided) for family or team members. User permissions such as User “Folder Only” feature assigns each user a dedicated folder within the root directory, named after their username, restricting them from viewing or modifying other directories. User Read Only and Disable Upload are additional permissions. FileRise also integrates with Single Sign-On (OIDC) providers (e.g., OAuth2/OIDC for Google/Authentik/Keycloak) and offers optional TOTP two-factor auth for extra security.
 
-- **Share Link Functionality:**
-  - Generate shareable links for files with configurable expiration times (e.g., 30, 60, 120, 180, 240 minutes, and a 1-day option) and optional password protection.
-  - Share links are stored in a JSON file with details including the folder, file, expiration timestamp, and hashed password.
-  - The share endpoint (`share.php`) validates tokens, expiration, and password before serving files (or forcing downloads).
-  - The share URL is configurable via environment variables or auto-detected from the server.
+- 🎨 **Responsive UI (Dark/Light Mode):** FileRise is mobile-friendly out of the box – manage files from your phone or tablet with a responsive layout. Choose between Dark mode or Light theme, or let it follow your system preference. The interface remembers your preferences (layout, items per page, last visited folder, etc.) for a personalized experience each time.
 
-- **User Authentication & Management:**
-  - Secure, session-based authentication protects the file manager.
-  - Admin users can add or remove users through the interface.
-  - Passwords are hashed using PHP’s `password_hash()` for security.
-  - All state-changing endpoints include CSRF token validation.
-  - Change password supported for all users.
-  - **Persistent Login (Remember Me) with Encrypted Tokens:**
-    - Users can remain logged in across sessions securely.
-    - Persistent tokens are encrypted using AES‑256‑CBC before being stored in a JSON file.
-    - On auto-login, the tokens are decrypted on the server to re-establish user sessions without requiring re-authentication.
+- 🌐 **Internationalization & Localization:** FileRise supports multiple languages via an integrated i18n system. Users can switch languages through a user panel dropdown, and their choice is saved in local storage for a consistent experience across sessions. Currently available in English, Spanish, French & German—please report any translation issues you encounter.
 
-- **Responsive, Dynamic & Persistent UI:**
-  - The interface is mobile-friendly and adapts to various screen sizes by hiding non-critical columns on small devices.
-  - Asynchronous updates (via Fetch API and XMLHttpRequest) keep the UI responsive without full page reloads.
-  - Persistent settings (such as items per page, dark/light mode preference, folder tree state, and the last open folder) ensure a smooth and customized user experience.
+- 🗑️ **Trash & File Recovery:** Mistakenly deleted files? No worries – deleted items go to the Trash instead of immediate removal. Admins can restore files from Trash or empty it to free space. FileRise auto-purges old trash entries (default 3 days) to keep your storage tidy.
 
-- **Dark Mode/Light Mode:**
-  - The application automatically adapts to the operating system’s theme preference by default and offers a manual toggle.
-  - The dark mode provides a darker background with lighter text and adjusts UI elements (including the CodeMirror editor) for optimal readability in low-light conditions.
-  - The light mode maintains a bright interface for well-lit environments.
+- ⚙️ **Lightweight & Self-Contained:** FileRise runs on PHP 8.1+ with no external database required – data is stored in files (users, metadata) for simplicity. It’s a single-folder web app you can drop into any Apache/PHP server or run as a container. Docker & Unraid ready: use our pre-built image for a hassle-free setup. Memory and CPU footprint is minimal, yet the app scales to thousands of files with pagination and sorting features.
 
-- **Server & Security Enhancements:**
-  - The Apache configuration (or .htaccess files) is set to disable directory indexing (e.g., using `Options -Indexes` in the uploads directory), preventing unauthorized users from viewing directory contents.
-  - Direct access to sensitive files (e.g., `users.txt`) is restricted through .htaccess rules.
-  - A proxy download mechanism has been implemented (via endpoints like `download.php` and `downloadZip.php`) so that every file download request goes through a PHP script. This script validates the session and CSRF token before streaming the file, ensuring that even if a file URL is guessed, only authenticated users can access it.
-  - Administrators are advised to deploy the app on a secure internal network or use the proxy download mechanism for public deployments to further protect file content.
-
-- **Trash Management with Restore & Delete:**
-  - **Trash Storage & Metadata:**
-    - Deleted files are moved to a designated “Trash” folder rather than being immediately removed.
-    - Metadata is stored in a JSON file (`trash.json`) that records:
-      - Original folder and file name
-      - Timestamp when the file was trashed
-      - Uploader information (and optionally who deleted it)
-      - Additional metadata (e.g., file type)
-  - **Restore Functionality:**
-    - Admins can view trashed files in a modal.
-    - They can restore individual files (with conflict checks) or restore all files back to their original location.
-  - **Delete Functionality:**
-    - Users can permanently delete trashed files via:
-      - **Delete Selected:** Remove specific files from the Trash and update `trash.json`.
-      - **Delete All:** Permanently remove every file from the Trash after confirmation.
-  - **Auto-Purge Mechanism:**
-    - The system automatically purges (permanently deletes) any files in the Trash older than three days, helping manage storage and prevent the accumulation of outdated files.
-  - **User Interface:**
-    - The trash modal displays details such as file name, uploader/deleter, and the trashed date/time.
-    - Material icons with tooltips visually represent the restore and delete actions.

 ## Installation & Setup
 
-### Manual Installation
+You can deploy FileRise either by running the **Docker container** (quickest way) or by a **manual installation** on a PHP web server. Both methods are outlined below.
 
-1. **Clone or Download the Repository:**
-   - **Clone:**  
+### 1. Running with Docker (Recommended)
 
-     ```bash
-     git clone https://github.com/error311/multi-file-upload-editor.git
-     ```
+If you have Docker installed, you can get FileRise up and running in minutes:
 
-   - **Download:**  
-     Download the latest release from the GitHub releases page and extract it into your desired directory.
+- **Pull the image from Docker Hub:**
 
-2. **Deploy to Your Web Server:**
-   - Place the project files in your Apache web directory (e.g., `/var/www/html`).
-   - Ensure PHP 8.1+ is installed along with the required extensions (php-json, php-curl, php-zip, etc.).
+``` bash
+docker pull error311/filerise-docker:latest
+```
 
-3. **Directory Setup & Permissions:**
-   - Create the following directories if they do not exist, and set appropriate permissions:
-     - `uploads/` – for file storage.
-     - `users/` – to store `users.txt` (user authentication data).
-     - `metadata/` – for storing `file_metadata.json` and other metadata.
-   - Example commands:
+- **Run a container:**
 
-     ```bash
-     mkdir -p /var/www/uploads /var/www/users /var/www/metadata
-     chmod -R 775 /var/www/uploads /var/www/users /var/www/metadata
-     ```
+``` bash
+docker run -d \
+  -p 8080:80 \
+  -e TIMEZONE="America/New_York" \
+  -e TOTAL_UPLOAD_SIZE="5G" \
+  -e SECURE="false" \
+  -v ~/filerise/uploads:/var/www/uploads \
+  -v ~/filerise/users:/var/www/users \
+  -v ~/filerise/metadata:/var/www/metadata \
+  --name filerise \
+  error311/filerise-docker:latest
+  ```
 
-4. **Configure Apache:**
-   - Ensure that directory indexing is disabled (using `Options -Indexes` in your `.htaccess` or Apache configuration).
-   - Make sure the Apache configuration allows URL rewriting if needed.
+  This will start FileRise on port 8080. Visit `http://your-server-ip:8080` to access it. Environment variables shown above are optional – for instance, set `SECURE="true"` to enforce HTTPS (assuming you have SSL at proxy level) and adjust `TIMEZONE` as needed. The volume mounts ensure your files and user data persist outside the container.
 
-5. **Configuration File:**
-   - Open `config.php` and adjust the following constants as necessary:
-     - `BASE_URL`: Set this to your web app’s base URL.
-     - `UPLOAD_DIR`: Adjust the directory path for uploads.
-     - `TIMEZONE`: Set to your preferred timezone.
-     - `TOTAL_UPLOAD_SIZE`: Ensure it matches PHP’s `upload_max_filesize` and `post_max_size` settings in your `php.ini`.
+- **Using Docker Compose:**
+Alternatively, use **docker-compose**. Save the snippet below as docker-compose.yml and run `docker-compose up -d`:
 
-### Initial Setup Instructions
+``` yaml
+version: '3'
+services:
+  filerise:
+    image: error311/filerise-docker:latest
+    ports:
+      - "8080:80"
+    environment:
+      TIMEZONE: "UTC"
+      TOTAL_UPLOAD_SIZE: "10G"
+      SECURE: "false"
+      PERSISTENT_TOKENS_KEY: "please_change_this_@@"
+    volumes:
+      - ./uploads:/var/www/uploads
+      - ./users:/var/www/users
+      - ./metadata:/var/www/metadata
+```
 
-- **First Launch Admin Setup:**  
-  On first launch, if no users exist, the application will enter a setup mode. You will be prompted to create an admin user. This is handled automatically by the application (e.g., via a “Create Admin” form).  
-  **Note:** No default credentials are provided. You must create the first admin account to log in and manage additional users.
+FileRise will be accessible at `http://localhost:8080` (or your server’s IP). The above example also sets a custom `PERSISTENT_TOKENS_KEY` (used to encrypt “remember me” tokens) – be sure to change it to a random string for security.
+
+**First-time Setup:** On first launch, FileRise will detect no users and prompt you to create an **Admin account**. Choose your admin username & password, and you’re in! You can then head to the **User Management** section to add additional users if needed.
+
+### 2. Manual Installation (PHP/Apache)
+
+If you prefer to run FileRise on a traditional web server (LAMP stack or similar):
+
+- **Requirements:** PHP 8.1 or higher, Apache (with mod_php) or another web server configured for PHP. Ensure PHP extensions json, curl, and zip are enabled. No database needed.
+- **Download Files:** Clone this repo or download the [latest release archive](https://github.com/error311/FileRise/releases).
+
+``` bash
+git clone https://github.com/error311/FileRise.git  
+```
+
+Place the files into your web server’s directory (e.g., `/var/www/html/filerise`). It can be in a subfolder (just adjust the `BASE_URL` in config as below).
+
+- **Composer Dependencies:** If you plan to use OIDC (SSO login), install Composer and run `composer install` in the FileRise directory. (This pulls in a couple of PHP libraries like jumbojett/openid-connect for OAuth support.) If you skip this, FileRise will still work, but OIDC login won’t be available.
+
+- **Folder Permissions:** Ensure the server can write to the following directories (create them if they don’t exist):
+
+``` bash
+mkdir -p uploads users metadata
+chown -R www-data:www-data uploads users metadata   # www-data is Apache user; use appropriate user
+chmod -R 775 uploads users metadata
+```
+
+The uploads/ folder is where files go, users/ stores the user credentials file, and metadata/ holds metadata like tags and share links.
+
+- **Configuration:** Open the `config.php` file in a text editor. You may want to adjust:
+
+  - `BASE_URL` – the URL where you will access FileRise (e.g., `“https://files.mydomain.com/”`). This is used for generating share links.
+  
+  - `TIMEZONE` and `DATE_TIME_FORMAT` – match your locale (for correct timestamps).
+  
+  - `TOTAL_UPLOAD_SIZE` – max aggregate upload size (default 5G). Also adjust PHP’s `upload_max_filesize` and `post_max_size` to at least this value (the Docker start script auto-adjusts PHP limits).
+  
+  - `PERSISTENT_TOKENS_KEY` – set a unique secret if you use “Remember Me” logins, to encrypt the tokens.
+  
+  - Other settings like `UPLOAD_DIR`, `USERS_FILE` etc. generally don’t need changes unless you move those folders. Defaults are set for the directories mentioned above.
+
+- **Web Server Config:** If using Apache, ensure `.htaccess` files are allowed or manually add the rules from `.htaccess` to your Apache config – these disable directory listings and prevent access to certain files. For Nginx or others, you’ll need to replicate those protections (see Wiki: [Nginx Setup for examples](https://github.com/error311/FileRise/wiki/Nginx-Setup)). Also enable mod_rewrite if not already, as FileRise may use pretty URLs for share links.
+
+Now navigate to the FileRise URL in your browser. On first load, you’ll be prompted to create the Admin user (same as Docker setup). After that, the application is ready to use!

-## Docker Usage
+## FAQ / Troubleshooting
 
-For users who prefer containerization, a Docker image is available
+- **“Upload failed” or large files not uploading:** Make sure `TOTAL_UPLOAD_SIZE` in config and PHP’s `post_max_size` / `upload_max_filesize` are all set high enough. For extremely large files, you might also need to increase max_execution_time in PHP or rely on the resumable upload feature in smaller chunks.
 
-### Quickstart
+- **How to enable HTTPS?** FileRise itself doesn’t handle TLS. Run it behind a reverse proxy like Nginx, Caddy, or Apache with SSL, or use Docker with a companion like nginx-proxy or Caddy. Set `SECURE="true"` env var in Docker so FileRise knows to generate https links.
 
-1. **Pull the Docker Image:**
+- **Changing Admin or resetting password:** Admin can change any user’s password via the UI (User Management section). If you lose admin access, you can edit the `users/users.txt` file on the server – passwords are hashed (bcrypt), but you can delete the admin line and then restart the app to trigger the setup flow again.
 
-   ```bash
-   docker pull error311/multi-file-upload-editor-docker:latest
-   ```
+- **Where are my files stored?** In the `uploads/` directory (or the path you set for `UPLOAD_DIR`). Within it, files are organized in the folder structure you see in the app. Deleted files move to `uploads/trash/`. Tag information is in `metadata/file_metadata`.json and trash metadata in `metadata/trash.json`, etc. Regular backups of these folders is recommended if the data is important.
 
-2. **Run the Container:**
+- **Updating FileRise:** If using Docker, pull the new image and recreate the container. For manual installs, download the latest release and replace the files (preserve your `config.php` and the uploads/users/metadata folders). Clear your browser cache if you have issues after an update (in case CSS/JS changed).
 
-   ```bash
-   docker run -d \
-   -p 80:80 \
-   -e TIMEZONE="America/New_York" \
-   -e TOTAL_UPLOAD_SIZE="5G" \
-   -e SECURE="false" \
-   -v /path/to/your/uploads:/var/www/uploads \
-   -v /path/to/your/users:/var/www/users \
-   -v /path/to/your/metadata:/var/www/metadata \
-   --name multi-file-upload-editor \
-   error311/multi-file-upload-editor-docker:latest
-   ```
-
-3. **Using Docker Compose:**
-
-   Create a docker-compose.yml file with the following content:
-
-   ```yaml
-   version: "3.8"
-   services:
-   web:
-     image: error311/multi-file-upload-editor-docker:latest
-     ports:
-       - "80:80"
-     environment:
-       TIMEZONE: "America/New_York"
-       TOTAL_UPLOAD_SIZE: "5G"
-       SECURE: "false"
-       PERSISTENT_TOKENS_KEY: "default_please_change_this_key"
-     volumes:
-       - /path/to/your/uploads:/var/www/uploads
-       - /path/to/your/users:/var/www/users
-       - /path/to/your/metadata:/var/www/metadata
-   ```
-
-**Then start the container with:**
-
-   ```bash
-   docker-compose up -d
-   ```
