Czkawka / Krokiet
A free duplicate finder: spots exact copies by content, resized lookalike photos, big files and empty folders, and sends the spares to the Recycle Bin.
What you can do with it
- Clear out copies from old phone backups
- Find WhatsApp-sized copies of your photos
- See your biggest files and empty folders
Worth knowingIts Delete button is permanent and shows the same message as Trash, so always use Trash. The old Czkawka GTK app is retired; the new app is called Krokiet.
