Doppelganger duplicate file finder

Find and remove duplicate files

Extra copies of photos, documents, and music eat disk space and slow backups. Doppelganger finds them — even when the file names are different — and lets you keep the copies you want.

How it works

1. Scan

Point Doppelganger at the drives or folders to search. Wizards walk you through the options.

2. Select

Use the Selection Assistant to keep the newest copy and mark the rest, or pick files yourself.

3. Remove

Send extras to the Recycle Bin or a holding folder so you can restore them if you change your mind.

Please note: Keep backups of important files. Be careful when removing duplicates so you do not delete a copy you still need. Some files are worth keeping more than once.
