Last updated: 2026-05-11

This document is the canonical inventory of all user-facing features implemented in the application. It serves as a guide to what the application can do and how each feature works.

---

1. Resource / Source Management

• Add multiple resource types: Connect Local folders, SMB (Windows share/NAS), FTP, SFTP, Google Drive, Dropbox, and OneDrive in a single interface.
• Resource profiles (quick-setup presets): Configure new folders using presets (Audio Library, Video Library, Photo Storage, Documents, All Files) that automatically apply optimal sorting, filtering, and display settings.
• Camera Photos Virtual Folder: A dedicated virtual folder to browse photos and videos taken by the device’s camera.
• Recent and Downloads: These default virtual folders are pre-configured with “Show all files” enabled to display documents and non-media files automatically.
• Virtual resource language sync: Virtual resources (All Images, All Videos, etc.) are automatically renamed when the app language changes.
• Per-resource settings: Customize supported media types, default sort mode, display mode, thumbnail loading, PIN access, and subfolder scanning per folder.
• Resource ordering: Rearrange connected resources on the main screen using drag-and-drop.
• Themed resource icons: Automatically assigned by type and connection source, or manually selected via the toolbar.
• Connection test: Verify network or cloud resource accessibility before trying to open it.
• Read-only mode: Protect critical folders by disabling file editing, deleting, and moving operations.
• PIN protection: Require a PIN code whenever a specific resource is opened.
• Network credential management: Encrypted vault for network passwords with a last-used tracking audit.
• Last browse position save & restore: Saves and restores the exact scroll position and last viewed file for every resource, opening directly into subfolders on resume.
• File list caching: Persists the file index in a local database to bypass network fetching on subsequent visits.
• Compact resource actions: An optional setting collapses per-resource action buttons into a single ⋮ overflow menu, reducing visual clutter on small screens and in portrait orientation. The overflow menu includes a dedicated Refresh action to test availability and update the file count for a single resource without opening it.

2. Media Browsing

• Extensive sort modes: Sort by Name, Date, Size, Type, Artist, Title, Duration, Date Taken, Random, or Manual order (ascending/descending).
• Sort mode memory: The sort mode is automatically saved per resource and restored on the next visit.
• Advanced filter panel: Filter items by filename, date ranges, size limits, or specific media types.
• Random file jump in player: A dedicated dice button in Audio and Photo profiles to jump to a random file without full shuffle.
• Multi-select: Select multiple files to batch copy, move, delete, or share.
• Show subfolders as items: Treat subdirectories as clickable entries mixed directly into the file list, or uncheck to flatten the view (recursive scan).
• Subfolder operations: Select, copy, move, rename, delete, and create subfolders directly in Browse for local, network, and cloud resources.
• Create Folder button in Browse toolbar - visible for writable resources with “show subfolders as items” enabled; creates a folder in the current browsed path.

• Intelligent thumbnail loading: Previews for photos and video frames; can be disabled per resource for large network directories.

Activates wherever the platform reports multi-window capability: ChromeOS / Chromebook (Googlebook), Samsung DeX, Android XR Home Space panels, and VR Quest 3+ panels. Enabled by default in those environments; on phones and tablets the setting stays off by default but can be turned on in Settings.

• Auto-download incoming links: Fetches media directly from shared HTTP, HLS, or DASH URLs, utilizing in-app WebView auth for any host (Instagram, TikTok, and beyond).
• Background link download queue: After auth is resolved, the app immediately returns the user to the source app (Instagram, browser…) and downloads the file in the background. A progress notification is shown during download; a result notification confirms the saved file name or reports failure. For sign-in-required hosts a “Sign in” action in the result notification re-opens the auth flow.

• When no sign-in exists for a host, the app offers to add one with three options: add now, skip this time, or never ask again for this site.
• Sites where the offer was permanently declined appear in the authorization settings list and can be re-enabled by deleting the entry.

24. Apps FMS Can Replace - Competitor Comparison

FastMediaSorter consolidates functionality that typically requires multiple separate apps into a single tool:

Photo Gallery (Replaces Google Photos, Simple Gallery, etc.)

Handles local photos plus full NAS/cloud access, scheduled automation, and cross-protocol file operations.

Video Player (Replaces VLC, MX Player, Nova)

Combines ExoPlayer codec support, PiP, and gesture controls with direct cloud/network streaming and integrated file management.

Audio / Music Player (Replaces Poweramp, Musicolet)

Offers background playback, sleep timer, and lyrics alongside the unique ability to stream directly from a NAS or cloud without syncing locally.

File Manager (Replaces Solid Explorer, MiXplorer)

Provides 24-thread SMB transfers, cross-protocol management, and completely native media players (no opening external intents).

NAS / Cloud Client (Replaces Cx File Explorer, Google Drive, Dropbox)

Unifies network protocols and major cloud providers with connection pooling, credentials audit, and direct cross-cloud file transfers.

PDF / EPUB Reader (Replaces Adobe Reader, Moon+ Reader)

Reads documents directly from network or cloud storage, integrating reading themes with native AR-style text translation and OCR.

Additional Replaced Tools

• FTP/SFTP Clients: Built-in alongside SMB.
• OCR Tools (Google Lens): Embedded directly into document and image viewers.
• Duplicate Finders: Cross-source, byte-for-byte SHA-256 detection.
• Slideshow Apps: Pulls images and background music from any network or cloud source.
