What OmniDiskSweeper leaves behind

Specific to OmniDiskSweeper

Dragging the app to the Trash does not remove its support folders, preferences, or update caches. These items remain in the hidden ~/Library directory until deleted separately. Since the utility does not store scan results between launches, these remaining files primarily consist of basic settings.

License: OmniDiskSweeper is free.

Preparing to uninstall OmniDiskSweeper

Ensure all active tasks are complete before removal. You should handle any identified large files while the interface is still accessible. Once the process is finished, quit the app to ensure a clean removal from the system.

Frequently asked questions

Yes. Folders marked “Yes, rebuilt automatically” are rebuilt automatically; removing them only makes the next start slower. Folders marked “Yes, settings reset” hold settings, which return to their defaults.

Where do I find the remaining preference files?

Use Finder > Go > Go to Folder and enter ~/Library to locate them.

Will removing the app delete the files I found during a scan?

No, deleting the app does not delete your own documents or data folders.
