macOS tells you that storage is full, but not what is taking up the space. DiskDude scans your drive in seconds and shows you the folders and files using it.
Each file is a box. Bigger boxes use more space.

Use the view that makes the most sense to you. Every view uses the same scan, so you can quickly find large files and folders.

The age map groups files by when you last changed them. It helps you find large files you may be ready to remove.

Remove apps with their leftover files and review every item before anything is deleted.

Scanning and duplicate checks happen on your Mac. No account, syncing, or analytics. DiskDude does not send your files or data to a server.
No trial, license key, email signup, or paid version.
DiskDude scans a drive or folder and shows you what is using the space. You can browse the results in nine views, open items in Finder, or add them to Cleanup.
A 256 GB home folder with about two million files takes around ten seconds on an Apple silicon Mac. Results appear while the scan is still running.
I made it for myself and it costs very little to share. It is free for now, with no trial or account needed. As I add more features, a paid tier may show up down the line, but everything you download today stays yours to keep.
Yes. You can scan your whole Mac, your home folder, or any connected drive or folder, including external SSDs and network drives.
No. DiskDude never deletes anything on its own. Cleanup lets you review every item before you remove it, and system folders cannot be added.
DiskDude is safe to open. The warning only appears because the app is not signed with a paid Apple developer certificate yet. If you see it, follow these steps. You only need to do this once.
