The Directory Inspector lets you drill down to individual files. Trace Agent notices apps moved to the Trash and suggests associated files for review. Risk indicators highlight data that may be shared by several apps. Eligible items can be held in quarantine and restored later. All sizes shown are examples; not every removal action can be undone.
