MindGems Fast Duplicate File Finder
The Free Fast Duplicate File Finder will find duplicate files in a folder, computer or entire network. The application will compare the content of the files and will find duplicates even if they are using different file names. The Professional version can find similar files regardless of their file types. It will analyze the file data in order to find duplicates and not just file attributes like name and size as the standard clone removers do. It uses advanced algorithms while searching for related files and provides accurate results, which is not true for the commonly advertised FUZZY search methods. The duplicate remover uses fast binary comparison algorithm and has internal preview supporting a lot of image, video, music and text file formats. It can also preview the common file formats.

DuoBolt
DuoBolt is a high-performance desktop application for finding duplicate files and similar photos, on macOS and Windows.
Exact duplicates are proven byte-for-byte by a multi-threaded BLAKE3 engine — never filenames, metadata or heuristics — across folders, codebases, archives, external drives and NAS volumes, with uniform accuracy at any data size.
A second engine groups photos that merely look alike: bursts, edits, re-saves. AI Curation ranks each group and names every measure it used — face sharpness, exposure, eyes open, framing. It runs entirely on your machine: no upload, no account, no network.
The workflow is intentionally simple:
• Choose the locations to scan
• Review results with clear contextual grouping
• Remove only what you select — deletions go to the system Trash and can be reverted
Free to use. Every download starts with 7 days of Pro; afterwards DuoBolt keeps scanning and showing everything it finds, and caps only what a single operation can move.
