Welcome to filesystem.online

Browse and manage local files directly in your browser. Open a folder, explore subfolders, preview images, videos, audio and PDFs, and edit text files—all within a single, self-contained page.

No uploads, no servers: your files never leave your device. Everything runs locally in your browser.

What you can do

• Open a writable folder (Chrome/Edge) or open a read-only snapshot.
• Navigate with a tree view and clickable breadcrumbs.
• See folders in Thumbs, List, or Details view with column sorting (Details).
• Inline previews for images, videos, audio, and PDFs; text editor with save.
• Create, rename, delete files and folders (writable mode).
• Keyboard shortcuts: F2 rename, Ctrl/Cmd+S save, Shift+Delete delete, Shift+D download, arrows for previous/next, F fullscreen.

Getting started

1. Click Open Folder to choose a writable directory (requires a browser that supports the File System Access API, such as Chrome or Edge), or use Open Read-only to pick a snapshot.
2. Browse the tree, select a folder to view its contents, or click a file to preview or edit.
3. Use the view and sort controls to change how items are shown.
