DiskX

DiskX scans a folder or a whole drive and shows you what's taking up the space, as a tree or a treemap. It's a new take on the DaisyDisk / Disk Inventory X kind of app.

It also tries to tell you what things are. DiskX recognizes many kinds of files and folders, things like Xcode's DerivedData, node_modules, Homebrew and pip caches, Steam games and downloaded AI models. For each one it says what created it and whether you'd lose anything by deleting it. When it doesn't recognize something and Apple Intelligence is turned on, it asks Apple's on-device model for a guess, and labels the answer as coming from AI.

The name comes from a disk sector editor I wrote for the Amiga in 1988. This one isn't a sector editor, but I kept the name.

What's new in 1.0.1

• Disk images that belong to macOS or the iOS Simulator, like the asset downloads under /System/Library, no longer show up under Archives & Installers. Files inside a folder DiskX recognizes are now counted as part of that folder.
• You can move through Recommendations with the keyboard. Up and down move between groups and items, right and left expand and collapse a group, and Return toggles it.
• Steam games are no longer listed twice (once for the game folder and once for the app inside it).
• Expanding a group in Recommendations no longer makes the inspector flicker.

Feedback

This is a beta, and I'd like to hear how it does on your disk: sizes that don't match what Finder says, folders it gets wrong or doesn't recognize, anything slow or confusing.

You can reach me at @stevex@mastodon.social on Mastodon. Please include the build number from About DiskX and your macOS version.

It doesn't currently delete anything

There's no delete or cleanup button in this build, and DiskX doesn't move or change your files. When you find something you want gone, Reveal in Finder takes you to it and you delete it there.

Privacy

DiskX doesn't use the network. There's no analytics and no crash reporting (yet). The AI explanations use Apple's on-device model, and your username is taken out of the path before the model sees it.

It doesn't check for updates on its own either. DiskX › Check for Updates… opens this page, and you can compare the build here with the one in About DiskX.
