What it does

WizTree reads an NTFS drive's file table directly instead of opening every folder, so a full scan usually finishes in seconds. It then lists the biggest folders, file types and individual files, with a treemap you can click into.

Delete or open anything straight from the results, which makes clearing space a few-minute job.

If you liked DaisyDisk's map of your drive, the treemap is the same idea. WizTree also has a Mac version now.

Good to know

  • The fast file-table scan needs administrator rights. Without them it falls back to a slower folder-by-folder scan.
  • At work? The free version is for personal use only.
