WebFileTree
A browser-based disk space analyzer.
Available at : webfiletree.pages.dev
Features
- Fast directory scanning using the File System Access API
- Visual treemap representation of disk space usage
- Detailed file and folder listings with size information
- Simple, intuitive interface
- 100% client-side processing - no data leaves your browser
Browser Compatibility
WebFileTree requires a browser that supports the File System Access API. Currently, this includes:
- Google Chrome (version 86+)
- Microsoft Edge (version 86+)
- Opera (version 72+)
Unfortunately, Firefox and Safari do not currently support this API.
How It Works
WebFileTree uses modern browser APIs to:
- Request access to a folder on your computer
- Scan the directory structure and calculate file sizes
- Build a visualization of the space usage
- Present the data in an interactive interface
All processing happens in your browser - no data is uploaded to any server.
Limitations
- Depth limitation: For performance reasons, WebFileTree limits recursion to 10 directory levels
- Browser permissions: The browser will ask for permission each time you analyze a folder
- Performance: Large directories with many files may impact browser performance
- Temporary access: Browser access to the filesystem is temporary and must be re-authorized in each session
