Nektony Duplicate File Finder Reviews

DuoBolt delivers fast, accurate duplicate detection for developers, system administrators, and power users managing large data volumes. A multi-threaded BLAKE3 engine handles codebases, media libraries, backup drives and network storage with consistent results at any size. On APFS volumes, clone detection ensures reported recoverable space reflects what the filesystem will actually free. Version 2.0 is a full rewrite in Rust, using roughly half the memory of the previous generation. It adds a second engine for near-duplicate images: perceptual hashing groups visually similar photos, and an on-device model ranks each group and reports the measures behind its pick. All inference runs locally: no uploads, no accounts, no network calls. RAW files are decoded directly, not through embedded previews. Select folders or drives, examine duplicates grouped by identical content, then filter after the scan by type, extension, path, tag or size. Files can go to the Trash, an archive, or a copy elsewhere. Every batch passes a review screen, and history restores removed files while a source copy survives. Unlike tools that guess from filenames or timestamps, DuoBolt compares cryptographic hashes of file content, so results are reproducible across scans and systems: version control cleanup, Docker caches, build artifacts, media assets. Native applications throughout: a Universal build for Apple silicon and Intel Macs, and separate x64 and ARM64 builds for Windows, so Snapdragon PCs run native code rather than x64 under emulation. Free to use, with no account: each installation begins with 7 days of unrestricted Pro features, after which it keeps scanning and reporting everything it finds, limiting only how many files a single operation moves.
