How ClearKun Protects You
- Hard-Locked Paths: ClearKun prevents the deletion of
System32,WinSxS, driver stores, and boot sectors. - Visual Risk Indicators: Every folder is marked with a color-coded safety tag (Green = Safe, Yellow = Review, Red = High Caution).
- Process Locking Detection: If a file is currently in use by an active program, ClearKun skips it gracefully instead of corrupting the file.
