VolumoraVolumora vs Disk Inventory X
Looking past Disk Inventory X? A treemap analyzer for today's macOS
Disk Inventory X helped make treemaps familiar to Mac users. It is free, released under the GPL, and draws the sizes of files and folders as a treemap whose layout algorithm is based on KDirStat, the same family of tools that inspired WinDirStat on Windows. Its official site lists version 1.3 for macOS 10.13 through 10.15.
If your Mac runs a newer macOS than that, check the developer's site before relying on it; we have not tested it on current releases and will not guess. Volumora is built for macOS 14 and later on Apple Silicon and Intel, keeps the treemap as its default view, and adds the tools you reach for after the map has shown you the problem.

Where Disk Inventory X is the better fit
No single app is right for everyone. These are the cases where we think staying with the other app is the better call.
- 01
Your Mac runs macOS 10.13 to 10.15
That is exactly the range Disk Inventory X 1.3 lists. Volumora needs macOS 14 or later, so on High Sierra, Mojave or Catalina, Disk Inventory X is the one to use.
- 02
You want free, open-source software
Disk Inventory X is GPL software. You can read the code, and it costs nothing. Volumora is a commercial app.
- 03
You are coming from WinDirStat
If you already know the KDirStat and WinDirStat style of treemap from Windows or Linux, Disk Inventory X will feel immediately familiar.
Why people switch to Volumora
Built for current macOS
Volumora is a native app for macOS 14 and later that runs on Apple Silicon and Intel. It asks for Full Disk Access so it can measure the folders modern macOS protects.
A treemap, plus two more views
The treemap is Volumora's default. Double-click to scan inside a tile, switch to ranked folder cards or a 3D landscape, and select any folder to see its size, share and largest files.
A parallel scanner
Volumora reads folders on all of your Mac's cores at once. In our benchmark it scanned 1.34 million files (54 GB) in 7.8 seconds, down from 66 seconds with its previous scanner.
Tools that act on the map
Smart Cleanup, Large & Forgotten files, a SHA-256 duplicate finder, an uninstaller with leftovers and Developer Cleanup. You review everything, and approved items go to the Trash.
Monitoring and Projects
Live CPU, memory, disk, network and battery, a menu bar panel with a health status, and a view of the dev servers running on your Mac.
