Reclaim your drive space, in seconds.

Everything you need to free up space

Built to find exactly what's eating your disk — then clear it without touching what matters.

Find the largest files

Recursively scan any drive or folder and instantly see your biggest files, sorted by size — including hidden and system files most tools skip.

Detect true duplicates

Find duplicate files by comparing their actual content (SHA-256), not just names or sizes — so identical copies are caught and look-alikes never are.

Delete safely

Send files to the Recycle Bin (recoverable) or delete permanently — always with a confirmation showing how many files and how much space you'll reclaim.

Break it down by file type

A tab per category — Videos, Images, Documents, Code, Engineering, Disk & VM — each sized biggest-first with a per-extension breakdown you can click to filter the grid.

Uninstall what you no longer use

The Installed Apps tab lists the programs on your machine so you can spot the heavyweights and remove them — without hunting through Windows Settings.

Live & responsive

Asynchronous scanning with a progress bar and cancel button, plus a live free-space readout — the interface stays smooth even on huge drives.

Clean, native & self-contained

A lightweight Windows desktop app — no clutter, no bundled extras, just the tool.

Why it's different

  • Sees hidden & system files. Caches, logs, and app data that bloat your drive but stay invisible in Explorer.
  • Content-based duplicate detection. A fast size → partial-hash → full-hash pipeline confirms real duplicates with certainty.
  • Recoverable by default. Deletes route through the Recycle Bin unless you choose otherwise — mistakes are undoable.
  • Truly portable. One self-contained .exe — no installer, no .NET runtime, no admin rights needed.
