Applications

DiskGOup builds an inventory of the installed applications and the space they occupy, and can uninstall them with the platform’s own mechanism.

How the inventory is built

Discovery is platform-native.

Platform	Source	Notes
macOS	.app bundles in /Applications and ~/Applications	The version is read from Contents/Info.plist (CFBundleShortVersionString, falling back to CFBundleVersion).
Windows	The Uninstall registry keys	HKLM\…\Uninstall, HKLM\…\WOW6432Node\…\Uninstall, HKCU\…\Uninstall.
Linux	.desktop entries in the XDG application directories	$XDG_DATA_HOME/applications, /usr/share/applications, /usr/local/share/applications, Flatpak exports.

On macOS the size is the whole bundle, measured with the allocated size rather than the logical one — the space the volume actually gives it.

The list is sorted by size, biggest first.

Uninstalling

diskgoup apps uninstall "Firefox"

About to uninstall Firefox
  rm -rf "/Applications/Firefox.app"
Continue? [y/N]:

✔ Firefox moved to the Trash.
Inventory rechecked; shared data was not cleaned.

Option	What it does
--yes / -y	Skip the confirmation prompt.
--dry-run	Show what would run, without doing it.

The name is matched exactly first, then by case-insensitive substring.

What actually happens

Platform	Mechanism
macOS	The bundle is moved to the Trash via send2trash.
Windows	The registered UninstallString is run.
Linux	The Exec line from the .desktop entry is run.
Anything else	The path is removed directly.

Afterwards the inventory is checked again — the same thing a real uninstall does.

Note

Shared data is never cleaned up. That is the uninstaller’s business, not DiskGOup’s. An application that left settings behind in ~/Library/Preferences leaves them there.

JSON output

diskgoup --json apps list

{
  "applications": [
    {
      "id": "/Applications/Xcode.app",
      "name": "Xcode",
      "path": "/Applications/Xcode.app",
      "size": 12998498999,
      "version": "16.2",
      "publisher": null,
      "uninstall_command": "rm -rf \"/Applications/Xcode.app\"",
      "source": "macos"
    }
  ],
  "total_size": 41234567890,
  "errors": []
}

errors carries the message when discovery failed on this machine — an empty list means everything was read.

In the desktop app

The Applications tab shows the same inventory with the footprint of each application, and offers the uninstall action from the same place.
