Clarity for everyday work
Find what matters to you
Filter by name, type, size, and more. Use Quick Look and reveal items in Finder for context.
Understand changes over time
Save scans, compare changes, or monitor the current folder as files change.
Getting started
- Choose a folder you have permission to scan.
- Explore large items in the map or list and open folders for detail.
- Preview files and understand their purpose before moving anything to Trash.
Common questions
Is allocated space the amount I can reclaim?
No. Logical size and filesystem-reported allocated space are different measures. Neither guarantees the space reclaimed by deletion.
Does it delete files automatically?
No. Moving an item to Trash requires confirmation in the app. You can restore it from Trash in Finder.
Can it scan every location?
The scope depends on the selected location and system permissions. Inaccessible items are skipped and reported; the app does not automatically elevate privileges.
