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.

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.
