Private duplicate finder
Duplet
Find exact duplicate files without sending anything away. Duplet scans locally, helps you review every copy, and moves only the files you choose to the Windows Recycle Bin.
Exact, not just similar
SHA-256 comparison identifies byte-for-byte matches rather than guessing from names, dates or appearance.
Scan your way
Search one folder, compare two locations or scan eligible drives for duplicate photos, videos, music and documents.
Review before removal
Preview supported files, keep the oldest, newest or largest copy, and see the recoverable space before taking action.
