Sweeper

Drag one to the Trash and its files stay scattered across your Library. Sweeper removes the app and every file it leaves behind, and shows you each one first.

• Every installed app, with its real footprint - See each app and the space it actually takes. Scan one for everything it left behind.
• Review every file before it goes- Every leftover grouped by kind and shown before it goes. Exact matches are selected, the rest is yours to confirm.
• Find what’s already gone - Files from apps you deleted long ago, found across your Library and tagged so you know what they are.
• Tidy what launches at startup - Every startup item grouped by app. Switch off what you never asked for, restore it anytime.
• Audit the extensions apps install - Share extensions, Finder plugins, and importers laid out per app. Turn off what you do not use.
