🛡 Safety net
Clean-ups go to the Recycle Bin first, so everything stays restorable.

Everything a full disk is hiding

DiskWise doesn't just tell you the drive is 92% full — it tells you why, and what to do about it.

See where the space went

A live storage map breaks every drive into apps & games, media, documents, and temporary files — filled in as the scan runs.

Smart suggestions

Temp folders, browser caches, forgotten installers, Windows Update leftovers, and year-old giant files — each with its real size and a clear safety label.

🛡

Safe by design

Everything you clean goes through the Recycle Bin, so it's restorable. Files in use are skipped automatically. Nothing is ever silently deleted.

Fast, native, tiny

A real Windows app — dark, fluent, and quick. Scans a full system drive in well under a minute on an SSD.

Find the giants

Your five biggest folders, surfaced automatically — so the 148 GB game library you forgot about has nowhere to hide.

You stay in charge

Every clean-up shows a full preview of what goes before anything moves. Untick anything. Cancel any time.

Three clicks to a lighter drive

No settings maze, no jargon. Install, scan, decide.

Scan

DiskWise reads your drive's layout and sizes every clean-up candidate — typically in under a minute.

Review

Suggestions arrive pre-sorted: green “Safe to clean” items ticked, “Review first” items left for your judgement.

Free up

One click sends it all to the Recycle Bin and shows exactly how much space came back. Change your mind? Restore from the bin.

Cleaners shouldn't be scary

Most “disk cleaner” tools ask for blind trust. DiskWise is built the opposite way — it assumes you'll want to double-check, and makes that easy.

  • Recycle Bin first — every file stays restorable until you empty the bin
  • Full preview of every file before any clean-up runs
  • System-critical folders are off-limits, always
  • Files in use are skipped, never forced
  • No account, no telemetry, no background service
