Official desktop application for FileShot.io — Fast, Private File Sharing with Zero-Knowledge Encryption.

Current version: 1.4.10 | Download latest release | Website

• Native desktop experience for Windows, macOS, and Linux
• Drag-and-drop files onto the tray icon for instant upload
• System tray integration — FileShot stays out of your way until you need it
• Background uploads — queue files and continue working
• The same zero-knowledge AES-256-GCM encryption as the web app

• Mounts a real virtual drive letter (e.g. F:\FileShot\) via WinFsp
• Drag files into the drive folder — they upload automatically
• Quota and usage stats shown in the Metrics dashboard
• Requires WinFsp installed

• Upload history, bandwidth used, files shared
• Local-only — no data sent to any server

• Local-first UI bundled inside the app
• Works without internet; queued uploads sync when connection resumes

• Auto-updates on startup — no manual installer downloads
• Recent uploads list with one-click copy of share link
• Clipboard integration
• Context isolation, CSP headers, node integration disabled (secure by default)

1. Download FileShot-Setup-1.4.10.exe
2. Run the installer — no admin rights required
3. FileShot launches automatically and appears in the system tray

Windows SmartScreen may warn "Windows protected your PC" because the app is currently unsigned. Click More info → Run anyway. After approximately 100 downloads from different IPs, Windows SmartScreen trust builds automatically.

1. Download FileShot-1.4.10.dmg
2. Open the DMG and drag FileShot to Applications
3. Right-click → Open if Gatekeeper blocks it

1. Download FileShot-1.4.10.AppImage
2. chmod +x FileShot-1.4.10.AppImage && ./FileShot-1.4.10.AppImage

The FileShot Drive requires WinFsp, a free Windows file system driver:

1. Download and install WinFsp (free, open source)
2. Open FileShot Desktop
3. Go to Settings → Drive → Enable FileShot Drive
4. A drive letter (default: F:) mounts as FileShot Drive
5. Drop any file into F:\ — it encrypts and uploads automatically
