02What Pro unlocks
01
Fast scan
Instead of opening every folder, Fast scan reads the NTFS Master File Table directly, so a whole drive is measured in seconds, including folders Windows normally will not let you see. Windows asks for administrator permission each time, and nothing on the drive is written.
02
Developer cleanup
Find node_modules, Rust target, Python virtual environments, .NET bin and obj, Gradle, Flutter, Next.js, Unity, Unreal and more next to their projects, with when each project was last worked on. Projects untouched for 30 days or more are pre-selected.
03
Limits
Set a size cap or an age limit on folders such as AI agent session logs, temp files, crash dumps or Downloads. You preview the exact files first, the oldest go to the Recycle Bin, and anything changed in the last 24 hours is never touched.
04
Watches
Watch any folder: “tell me when it grows by 1 GB in a day” or “when it passes 20 GB”. An optional hourly check takes a few seconds, needs no admin, and reports sudden growth as a Windows notification.
05
Uninstall
Running the uninstaller is free. Clearing the leftovers in one step is Pro.
06
AI tools
Seeing your AI tools is free. Stopping them is Pro.
07
History and forecasts
Daily snapshots and what changed between the two latest are free. Comparing any two snapshots and forecasts are Pro.
08
Duplicates
Finding duplicates is free. Sharing one copy is Pro.
