Comparison
Dup vs dupeGuru: finding duplicates that are not byte for byte
dupeGuru is a free, open source duplicate finder that matches files by name, including near matches, or by their contents. Dup matches photos and videos by what they show, so a copy that was re-encoded, resized or renamed is still found.

The facts
- dupeGuru is free and open source. Its interface has changed little in years, and scans of very large libraries can be slow.
- Comparing names or bytes misses a video that was exported again at another resolution, because every byte of the file changes.
- Dup fingerprints each video's frames on your Mac and shows each group side by side before anything is removed.
One clip in three files, a 4K MOV, a 1080p MP4 and a copy, found by Dup as one group even though their names, sizes and formats differ.
