A modern Norton Commander dual-pane file manager that runs entirely in the browser.
Features
- Dual-pane layout -- independent left/right panels, each browsing its own directory
- Two file system backends -- browser-private storage (OPFS) out of the box, plus optional native filesystem access via the File System Access API
- Cross-adapter operations -- copy and move files between OPFS and your local disk seamlessly
- Built-in text editor -- view (F3) and edit (F4) text files inline with save support
- Classic keyboard workflow -- F-key toolbar, Insert/Space selection, Tab to switch panels, and all the shortcuts you remember
- Sorting -- click column headers to sort by name, extension, size, or date
- Context menu -- right-click (or long-press on mobile) for quick actions
- Mobile support -- swipe between panels, responsive layout, installable PWA
- Offline-capable -- service worker caches all assets for full offline use
- Zero dependencies -- vanilla JavaScript, no frameworks, no build step
Quick Start
Serve the directory with any static file server:
# Python python3 -m http.server 8000 # Node npx serve . # PHP php -S localhost:8000
Then open http://localhost:8000 in your browser.
