• See where your space went. Scan a drive or your home folder. The Dashboard shows free space, the folders at the top of the drive, and what kind of files fill it.
• Know what it is. Common space hogs are named in plain words: browser and app caches, temp folders, package caches, build output, emulators, AI models, cloud folders. In temp and cache folders, Underbrush says which app made each part.
• Sorted into piles. Safe to clear, Your call, Cloud and Leave it.
• Free up in one click, or pick item by item in Clean up. You always see the list and the total first.
• Careful by default. Recent files, files in use, git repositories and caches in use by a running build are left alone. Cloud files are made online-only, never deleted.
• History of every scan and clean-up.
• System tab: how hard your computer is working, across disk, memory and CPU.
• Fits your screen. Picks a size on first run; Ctrl + and Ctrl − change it.
• Windows and macOS.
