What it does

Explore lets you walk the drive one folder at a time, biggest first. For each folder it shows the size, the pile, what kind of files it holds, and how much inside is safe to clear.

Pick a folder and the panel on the right explains it:

  • What it is and which pile it's in, with a short description for folders Underbrush recognises.
  • Last changed: when anything inside was last written.
  • What's inside: for temp and cache folders, who made each part (Google Chrome, the Visual Studio installer, installer leftovers, temporary tmp… folders, and so on), with a verdict for each. A git repository inside is marked as kept.
  • What kind of files: the folder split by kind.

How to use it

  1. Open the Explore tab, or click a row on the Dashboard.
  2. Click a folder to go into it. Use the path at the top to go back up.
  3. Select a folder to see its details on the right.
  4. Click Add to clean-up to tick it in the Clean up list (or Make online-only for a cloud folder). Click again to take it out.
  5. Click Show in File Explorer (Finder on a Mac) to open the folder yourself.

Only folders Underbrush recognises can be added to the clean-up. To remove your own files, use File Explorer or Finder.

Troubleshooting

  • A folder shows no "Add to clean-up": it's in Leave it or Unsorted, so Underbrush won't clear it.
