Dupe Sweep: Duplicate File Finder for Mac

A free Mac app that finds exact duplicate files and lets you choose which copy stays.

Dupe Sweep compares what is inside your files, not their names. It shows the keep rule before anything moves, so you decide which copy of each file stays. On 1.39 TB of video, photos and documents it finished in about four minutes. A duplicate finder from the Mac App Store took 1 hour 23 minutes on the same files and found the same duplicates.

Safe by design: files go to the Trash, and Put Everything Back undoes the whole move

Seven visible keep rules, folder pinning, and a check just before each file moves

Open source under the MIT license, no account, no tracking, no upload

Read the full test, with the numbers and the keep rules, in How to Delete Duplicate Files on a Mac: Which Copy to Keep. Download Dupe Sweep 1.0 (free, macOS 14 or later, under 2 MB). The source code is on GitHub. If it saved you time, you can buy me a coffee.
