See what takes up space on your disk, and clean it up.
For macOS, Windows and Linux. Fast, local, no network access.
Inspired by DaisyDisk.
- Scan disks and folders. A scan uses every core. You can scan several disks or folders at once, and pause or stop each scan from its row.
- Sunburst chart. Each ring is one folder level, colored by file type: video, images, audio, archives, disk images, documents, code, apps, libraries and caches. Hover a segment for its size and share. Items too small to show are grouped together.
- True sizes. Counts the space files use on disk, not their nominal length. Hard links and cloned or reflinked copies count once.
- Hidden space. Space the scan can't see gets its own segment: snapshots, purgeable space on macOS, folders it couldn't read and file system metadata. Select it to see the likely causes and how to free that space.
- Search. Type a name to narrow the list to matching items. The chart highlights where they are.
- Clean up. Collect files and folders to delete. The chart shows your disk as it would be without them. System locations can't be collected.
- Open results. Going back to the start page keeps each result open, so you can switch between scans without scanning again.
Download the file for your system from the latest release.
| System | File | First launch |
|---|---|---|
| macOS 11+ | .dmg |
Drag the app to Applications. It is signed and notarized, so it opens without a warning. |
| Windows 10+ | .zip |
Run disk-analyzer.exe. If SmartScreen appears, click More info → Run anyway. |
| Linux | .tar.gz |
Run ./install.sh to add it to your app menu, or run ./disk-analyzer directly. |
Full disk scans: on macOS, give the app Full Disk Access (System Settings → Privacy & Security). On Windows and Linux, run it as administrator or root. Folders it can't read are counted as hidden space.
Requires Rust.
