Why we built NestFiles this way
Most duplicate finders are judged on one number: how fast they scan. We optimized for a different moment — the one right before you act on what they found.
Speed isn't the risk. Certainty is.
A duplicate finder can be fast and still get you into trouble, because the dangerous moment isn't the scan — it's the delete. We built NestFiles around making that moment slower and safer, not faster and riskier.
Preview first, always
Before anything moves, NestFiles shows you exactly what it found and what it proposes to do. You look at the actual list, not a summary count, before confirming anything.
Quarantine, not deletion
Confirmed duplicates move to a reversible quarantine backed by a local manifest, not straight to your recycle bin. If something turns out to matter, the Restore Center can bring it back.
Local-first, not "trust our servers"
Your files, and the metadata NestFiles derives from them, never leave your PC. There's no account to create and no server-side copy of your file list to worry about.
Where we're honestly slower
We don't hide it: tools built purely for scan speed, like Czkawka, can be meaningfully faster on a cold or warm cache. We think the extra seconds are worth it for what you get back — see the full comparison with numbers.
