How to use the folder size analyzer

  1. Click Choose a folder and allow your browser to read it.
  2. See the total size, the biggest subfolders, file types and the 20 largest files.
  3. Clean up the space hogs in your file manager.

Find out why your Downloads, Desktop or project folder is so big — old videos, installers, ZIP archives and duplicate backups usually top the list. Only file sizes and names are read; contents are not opened and nothing is uploaded. Note that hidden system files may be skipped by your browser.
