How Does DupScan's Scanning Compare to Nektony's?

DupScan uses a two-pass SHA256 hashing optimization that scans a 4KB partial hash first and only performs full-file hashing on candidates, making scans significantly faster. DupScan also uses priority scanning to process high-value folders like Downloads and Documents first.

Nektony Duplicate File Finder uses hash-based comparison to detect duplicates, which is fundamentally sound. DupScan's advantage is in optimization — the two-pass approach eliminates most non-duplicate files during the quick partial hash phase, avoiding expensive full-file reads. Combined with parallel processing across all CPU cores and CryptoKit hardware acceleration on Apple Silicon, DupScan completes full-disk scans faster.

Priority scanning is another DupScan advantage. Downloads, Desktop, Documents, Pictures, Movies, and Music are scanned first because they contain the most likely duplicates. Results appear within seconds of starting a scan. See all scanning features in detail.

How Do the Free Tiers Compare?

DupScan Free provides unlimited scanning and full duplicate detection with no deletion capability. Nektony's free tier allows a limited number of deletions before requiring a paid upgrade. Both apps let you see your duplicates before paying, but DupScan never restricts scanning.

Nektony's approach of allowing limited free deletions can be frustrating — users discover their duplicates, start cleaning, and hit a paywall mid-process. DupScan separates scanning (always free, always unlimited) from deletion (requires Pro). You can fully assess your duplicate situation and make an informed purchase decision.

Which App Provides Better History and Restore?

DupScan records every trashed file in a persistent History tab with the original path, file size, and deletion date. One-click restore puts files back in their original location. Nektony offers limited restore capability without the same level of detail and persistence.

Safe deletion requires a safety net. DupScan's History persists across app launches and shows a clear status for each file — whether it is still in Trash and restorable, or has been emptied. The summary view shows total files trashed, total space recovered, and count of restorable files across all sessions.

This level of deletion tracking is especially important when cleaning large numbers of duplicates. You can confidently delete hundreds of files knowing that every action is recorded and reversible. Learn more about safe deletion in our duplicate file guide.

Should You Choose DupScan or Nektony?

DupScan is the better choice for users who want optimized two-pass scanning, complete deletion history with restore, zero data collection, and a straightforward $9.99 one-time price. Nektony is worth considering if you prefer trying limited deletions before committing to a purchase.

Both apps solve the same core problem, but DupScan's technical optimizations and privacy-first design give it an edge. Two-pass hashing, priority scanning, automatic system file protection, and persistent History with restore provide a more thorough and safer duplicate cleaning experience. DupScan's fully offline architecture means your file data never leaves your Mac.
