Duplicate Photos Fixer Pro vs fclones

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.

fclones is a free command-line utility for locating groups of identical files and handling redundant copies. It runs on Linux, macOS, and Windows, and can scan multiple directory roots, standard-input file lists, and mounted or removable devices. Search controls include recursion limits, glob and regular-expression filters, and minimum or maximum file sizes. It can compare files using size, inode or file identifiers, prefix and suffix hashes, and full-content hashes. Results are available as text, fdupes-compatible output, CSV, or JSON. Once duplicates are identified, fclones can remove or move them, or replace them with soft or hard links. On supported file systems, it can deduplicate file data with native copy-on-write reflinks, a capability unavailable on Windows. Users can inspect and alter duplicate lists before removal, and dry-run mode reports changes without executing them. The Rust implementation parallelizes I/O and CPU-heavy work and adjusts processing for SSDs and HDDs. Optional persistent hash caching can help repeated scans and resumed work; the project is released under the MIT license.
