Duplicate Photos Fixer Pro vs jdupes

Duplicate Photos Fixer Pro finds exact duplicates and similar-looking images, helping users organize photo libraries and recover storage. It can automatically mark photos for deletion, then group detected images so they can be previewed before removal. The product page lists support for JPG, PNG, TIFF, GIF, RAW, PSD and HEIC/HEIF files. On Windows, scans can include a PC, Dropbox without downloading its photos, and Lightroom Classic or Picasa libraries. Windows deletions go to the Recycle Bin, but duplicates on external drives are deleted directly. The maker lists Windows, macOS, iOS and Android versions; its Windows edition supports Windows 7 and later, in 32-bit and 64-bit versions. The Windows trial is available once per user and permits removal of up to 15 duplicate photos. The Windows license costs $39.95 a year, billed annually, for one year. A 60-day money-back guarantee is offered to customers who contact the company within 60 days of registration.

jdupes is a free utility for finding and handling exact duplicate files on Linux, macOS, and Windows. It identifies files that are fully identical rather than matching images, sounds, or other formats by similarity. Matching can use file size, hashes, and byte-for-byte comparison, with optional partial-hash matching. The project says it checks matching data after hashing to reduce the chance of false matches from hash collisions. Found duplicates can be reviewed before deletion, deleted without prompting, linked, summarized, or handled through copy-on-write deduplication. On Linux and Unix, the instructions use command-line directory paths; the project also provides a native Windows port, including support for Unicode. Docker use is documented, and standard output can feed shell scripts. A database can retain scan metadata for repeat runs, though the project labels that feature as under development and notes quirks. The README warns that quick matching skips byte-for-byte checks and can classify non-duplicates as duplicates. It also warns that disabling file-change checks creates a security vulnerability, especially when linking or deleting. jdupes is distributed under the MIT License.
