# Duplicate finder for Mac: Files that exist twice, confirmed byte for byte.

> Find duplicate files on your Mac from the notch. Matches are confirmed with a full SHA-256, APFS clones are recognised, and extra copies go to the Trash.

The same PDF in Downloads, on the Desktop and in a client folder. The same video exported twice. Duplicates pile up quietly.

ctrlhq compares files of the same size in two quick passes, then confirms every match with a full SHA-256 hash. It keeps the oldest copy and stages the rest for the Trash.

## What you get

- **Confirmed byte for byte.** Two quick passes over the first and last bytes, then a full SHA-256. Names don't matter.
- **Keep one, stage the rest.** The oldest copy is kept. Stage the others for a whole set in one click, or pick copies yourself.
- **APFS clones spotted.** Copies that share their storage on APFS free nothing when deleted, so ctrlhq marks them and leaves them out of the total.
- **Hard links left alone.** Two names for the same file aren't counted as a duplicate.
- **Choose a minimum size.** Only look at files over 100 KB, 1 MB, 10 MB or 100 MB.
- **Your files, not app data.** ctrlhq skips ~/Library, app bundles, node_modules and hidden folders, where copies are there on purpose.

## FAQ

### Which copy does ctrlhq keep?

The oldest one, by creation date. You can see every copy and change what's staged before anything moves.

### Are duplicates deleted?

They're moved to the Trash, so you can drag them back out if you need to.
