Prism File Explorer (techflyers' fork)

A modern, feature-rich, and lightweight file manager for Android, built entirely with Kotlin and Jetpack Compose.

Delivering a seamless file management experience with a beautiful Material Design interface.

Key features:

Modern User Interface & Navigation

• Jetpack Compose & Material 3: Fully declarative, highly responsive, and beautiful layouts with automatic light/dark theme support.
• NFile Navigation Drawer: Quick-navigation sidebar for accessing the Dashboard, System Root, Recycle Bin, and server/network configuration wizard.
• Multi-Tab Layout: Seamlessly open, navigate, and manage multiple folders at once.
• Intuitive Breadcrumbs: Quick hierarchical folder traversal.

Advanced File Management

• Comprehensive Operations: Copy, cut, paste, rename, delete, batch select, and inspect detailed properties of files and folders.
• Interactive Clipboard FAB: An ExtendedFloatingActionButton dynamically shows "Paste here" / "Move here" options for pending clipboard items.
• Intelligent Duplicate Renaming: Same-folder copy operations automatically bypass directory validation and append a (copy) suffix.
• Recycle Bin Restore: Preserves the original file paths by writing a metadata.json sidecar, allowing you to restore deleted files to their exact source.
• Privileged Explorer Mode: Complete root and Shizuku integration to display file sizes, timestamps, and contents count for restricted folders.

Private Wallet (Vault)

• Secure PIN Protection: Set up a custom 4-digit PIN with a haptic-feedback keypad to lock your sensitive files.
• Cryptographic Scrambling: Encrypts and decrypts files using SHA-256 password salting and custom byte XOR-scrambling.
• Seamless Temporary Viewing: Decrypts files temporarily to the cache for inline viewer viewing and automatically scrubs them on exit.

Servers & Remote Connections

• Local FTP Server: Run a background FTP server via a persistent FtpForegroundService with notification-area status controls.
• Web Sharing Portal: Host an offline directory listing server, support chunked/range media streaming for browser viewing, accept remote POST file uploads, and establish secure public tunnels via SSH client port-forwarding to localhost.run.
• Local QR Code Generation: Swapped online sharing APIs for the ZXing library to render secure, local QR codes for Web Sharing URLs without transmitting data.
• Remote Connection Wizard: Configure and save connections for FTP, SFTP (via sshj), WebDAV, and simulated SMB/LAN servers.
• Remote Explorer: Manage remote archives directly, download, upload, create folders, and delete remote files.
