Let OptiClear find these files
Doing this by hand is slow and easy to get wrong. OptiClear scans your Mac, lists every related file with its size, and moves only what you select to the Trash, so you can still restore it. Scanning is free; cleaning requires OptiClear Pro.
Frequently asked questions
Is it safe to delete these files manually?
Usually, yes. Files in ~/Library/Caches are created by the app and can be removed once it has quit. Risk level: . Move them to the Trash rather than deleting them permanently, so anything you still need can be restored; the app recreates what it requires.
Will I lose my settings or data?
Manual removal of the support folder resets the app to defaults. To keep settings, back up the location first or use OptiClear's selective cleanup.
