Built for careful cleanup
Duplicate cleanup can damage a project if it is rushed. Twinfinder keeps users in control with visible recommendations, blocked-file safeguards, safe Trash moves, undo support, and exports for review.
Mac App · Version 2.2
Twinfinder
Find duplicate files, similar photos, repeated audio, and overlapping folders, then review a clear cleanup plan before anything moves to Trash.
Cleanup Review Plan New in 2.2
Twinfinder now turns every cleanup into a reviewable plan. The plan shows the kept file, files selected for removal, blocked items, recoverable space, match type, risk level, and a plain-language reason for each group. Users can copy the plan as Markdown for an audit trail.
