dskDitto vs Duplicate Photos Fixer Pro

dskDitto is a duplicate-file detector for Linux and macOS with a terminal interface by default and an optional experimental Raylib graphical interface. It scans local filesystem paths and directories using parallel processing, with optional virtual filesystem directories. Matching can use SHA-256, BLAKE3, exact filenames, or fuzzy content similarity; fuzzy mode starts at a 75% similarity threshold and disables automatic removal and link actions. Scan filters cover file size, directory depth, hidden files, symlinks, virtual filesystems, and filesystem boundaries. You can preview files, exclude folders, and use automatic selection. Results export to CSV, JSON, or plain text. With the explicit remove option, extra copies can be deleted or replaced by symlinks or reflinks. Reflinks require supported copy-on-write filesystems such as APFS, Btrfs, or XFS with reflink enabled. Source installation requires Go 1.22 or later; GUI builds also require Raylib and CGo. The project is free and released under the Apache license.

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.
