How to use
- Choose a folder.
- Select treemap tiles (or folder names in the table below it) to drill into subfolders; the path above the treemap goes back up.
- Check the Largest files and By file type tabs, and export any view as CSV.
Worked example
The sample Downloads listing (18.4 GB) shows installers (.exe, .dmg) using 9.1 GB, the largest file type; the biggest single tile is a 2.4 GB installer.

Questions
Are my files uploaded or opened?
No. The browser lists names, paths and sizes for the folder you select; no file contents are read and nothing leaves your device.
Can I delete large files from here?
No. Browsers cannot delete files on disk. Use the largest files list to find them, then remove them in your file manager.
