jdupes is a powerful duplicate file finder and an enhanced fork of ‘fdupes’. The program was forked from fdupes.
jdupes only works on 100% exact matches. It does not have any sort of “similarity” or “fuzzy” matching, nor does it know anything about any specific file formats such as images or sounds. Something as simple as a change in embedded metadata such as the ID3 tags in an MP3 file or the EXIF information in a JPEG image will not change the sound or image presented to the user when opened, but technically it makes the file no longer identical to the original.
jdupes searches the given path(s) for duplicate files. These files are found by comparing file sizes, then partial and full file hashes, followed by a byte-by-byte comparison. The default behavior with no other “action options” specified (delete, summarize, link, dedupe, etc.) is to print sets of matching files.
jdupes is not a drop-in compatible replacement for fdupes.
Features include:
- Fast alternative to fdupes.
- Good stability.
- Block-level data deduplication and control over which file is kept when a match set is automatically deleted.
- Code is written with data loss avoidance as the highest priority.
- Cross-platform support – runs under Linux, Mac OS X, and there’s a native Windows port.
