Only exact copies
Two files are grouped only when their contents match completely. A renamed copy is caught, and a different file with the same name isn't.
APFS clones aren't counted
When you duplicate a file in Finder on APFS, the copy shares the original's storage until one of them changes. Deleting it frees nothing. Broom detects clones, marks them Shares space, and leaves them out of the total, so the number it shows is space you'll actually get back.
Keep one, queue the rest
Each group lists every copy with its path and modified date. Keep first keeps the oldest copy and queues the others; one button does that for every group at once. Quick Look and Reveal in Finder are on each file if you want to check first.
Choose which folder to search and skip small files under 100 KB, 1 MB, 10 MB, 100 MB or 1 GB. Duplicates come from the scan you already ran, so nothing is read twice.
Photos, downloads and backups
The usual sources are photos exported more than once, the same installer downloaded twice, and old manual backups of folders you still have. More in our guide to finding duplicate files on a Mac, or see how Broom compares with Gemini 2.
Questions
What is the best duplicate file finder for Mac?
One that matches by file contents rather than names and understands APFS clones. Broom does both and sends removed copies to the Trash.
Does Broom find similar photos?
No. It finds exact duplicates only. Edited or resized versions of a photo are different files.
Will deleting duplicates break anything?
Copies inside app bundles or libraries can be needed. Broom keeps one copy of every group, and everything removed goes to the Trash so you can put it back.
Does Broom find duplicates in Photos library?
It finds identical files anywhere it scans, but remove duplicates inside the Photos library from the Photos app itself.
