How cleanup works
Check the selected project’s manual; X, Xs, and Y do not share a guaranteed cleanup contract. Confirm each file’s path and purpose before removing it. Items in Trash still occupy storage until it is emptied.
How NullDisk compares
A native Mac disk analyzer with radial and treemap views, SSH/cloud sources, and development cleanup. Consider it for Git-aware development cleanup or a workflow spanning local, SSH, and cloud storage. The separate CLI provides terminal browsing and structured reports.
All direct Mac features are free with reminders; an optional one-time license removes them.
NullDisk has no content-based duplicate finder. Its Mac app sends anonymous usage telemetry; read the privacy policy if that affects your choice.
