duplicate-finder
Find and delete duplicate files on your Mac — without touching a single terminal command.
The problem
Your Mac is full. You open Storage and see "Documents: 48 GB" — but you have no idea why. Somewhere in there are hundreds of duplicate photos, downloads saved twice, and files copied across folders years ago. Finding them manually is impossible.
What this does
duplicate-finder is a menu bar app that scans any folder, finds exact duplicates, and lets you delete them safely — with a clear preview before anything is removed.
- Scans by content, not just filename
- Groups duplicates so you always keep one copy
- Shows exactly how much space you'll free up
- Move to Trash, never permanent delete
How it works
- Click the menu bar icon
- Choose a folder to scan (Downloads, Documents, Desktop — or your whole home folder)
- Review grouped duplicates with file size and location
- Select which copies to remove
- Click Move to Trash — done
No files are deleted without your confirmation. Ever.
Requirements
- macOS 13 Ventura or later
- Apple Silicon or Intel
Privacy
All scanning happens on your device. No files, filenames, or metadata ever leave your Mac.
