KDiskFree For Linux

If you're a KDE Plasma user, then you probably already know what KDiskFree is as its name is pretty self-explanatory. For those who are not fans/users of Plasma, KDiskFree is a tiny utility designed to display how much free disk space you have on your system.

To be more precise, there's a lot more this app does. It actually displays all the available file devices along with information on their total capacity, available free space, their type, as well as their mount point.

KDiskFree is a straightforward app by all accounts. The app's main window is comprised of a top menu bar and the main area where all the devices are displayed.

Each device has an icon (depicting the type of storage unit it is - hard drives, external drives, floppy or CD drives, etc.), the device name, the filesystem type, total size, mount point, the free disk space, the percentage of space used (displayed both as a number and as graph).

From the app's contextual menu (right-click menu), you can mount and unmount selected devices. From the app's Settings section, you can also add custom mount commands, as well as change the update frequency (by tweaking the value in the box - in seconds).

Whether if not KDiskFree is right for you or not highly depends on your expectations. KDiskFree is a very simple application that displays how much free space you have on your disks or devices, and not much else.

There are more advanced apps of this sort out there, but the thing that makes KDiskFree so good is that it's nicely integrated with the Plasma environment (it's part of the Kontrol Center under Information -> Storage Devices). The fact that you can install the app from various sources (Flathub, Snapcraft, or directly from the KDE Store) is also a good thing.
