Scan smart.
Clean safely.
NYCTAVIS is a local-first Windows utility that finds junk, duplicate files and reclaimable space — and cleans only what you approve.
NYCTAVISEverything to reclaim your disk
A focused toolkit that scans, finds and cleans — always with your confirmation.
Deep disk scan
Quick, full or folder-picked scans map exactly what is taking up your space.
Duplicate finder
Content-based hashing detects true duplicate files, even with different names.
Guided cleanup
Temporary files, caches, the Recycle Bin and Windows cleanup tools — with clear previews and confirmations.
Reclaim space
Review recoverable space and apply the available actions with clear confirmation.
Safe by default
Potentially destructive actions require confirmation. Managed quarantine protects reversible flows.
Private & local
Everything runs on your PC. No cloud upload or telemetry. Free mode needs no NYCTAVIS account.
Clean, calm, in control
A modern interface in English, Spanish and French.
Your files never leave your PC
NYCTAVIS is local-first by design. It reads your disk to help you clean it — and that is where everything stays.
- ✔No cloud. Analysis happens entirely on your machine.

- ✔No NYCTAVIS account. Free mode works without sign-up; Microsoft Store may require its account for Pro purchases.
