dskDitto vs Duplicate Files Fixer

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 Files Fixer scans computers, external drives, and cloud storage for duplicate photos, videos, music, documents, and other files. It can compare file contents as well as names, size, creation and modification dates, and similar names, so identical files can be detected even when their names differ. Users can preview grouped results and choose what to delete; Auto Mark selects extra copies while leaving one in each group unmarked. Folder exclusions are available. On Windows, it can scan Google Drive and Dropbox after sign-in and folder selection. The free version scans unlimited files and removes up to 15 duplicates in one go; additional deletions must be made one at a time. The paid version removes all marked duplicates in one click. It is listed for Android, macOS, and Windows. The paid plan is €35.95 a year, billed annually at a discounted price; the page also lists €64.95 as the product price. PC deletions go to the Recycle Bin by default, but USB and network-drive deletions do not.
