filesystem.online

Local FileSystem Viewer in your browser

filesystem.online lets you open a folder from your computer and browse its contents in a clean, desktop-like interface. Navigate with a tree view, switch between Thumbs, List and Details view, and quickly preview images, video, audio, PDFs and text files.

No uploads, no servers: your files stay on your own machine. All logic runs locally in this one HTML page.

You can save the viewer as an HTML file and keep using it completely offline. It is donationware: free to use, with optional support via PayPal, Ko-fi or Buy Me a Coffee if you would like to give back.
