Description Riccardo Robecchi 2025-06-25 10:16:38 UTC
SUMMARY
The new "Disks" section introduced in Plasma 6.4 would be a lot more useful if it also showed the total space available (i.e. the partition size), rather than only showing the used space. As an example, in the screenshot you can see that the widget states "613.7 GiB", an information which is however made a lot less useful by not displaying the total size of the partition (712.3 GiB) as the user does not know how much of the partition is still free - which, I would argue, is the main point of such a widget.
In other words, the information that is really important is how much free space there is left; giving the user only the occupied space without giving them the total one (so that they can calculate how much free space is still left) is not useful.

STEPS TO REPRODUCE
1. Open System Monitor

OBSERVED RESULT
The "Disks" widget only shows the occupied space.

EXPECTED RESULT
The "Disks" widget shows the occupied space and the total space.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE neon

You can edit the Disk Widget to make it show the total space as well. (With the little edit button on the top right). Check above attachment to see what it looks like.

Although the edit is trivial, I think it would be better if the widget was like that by default.
Comment 4 Riccardo Robecchi 2025-08-08 10:48:47 UTC
Thanks for the suggestion. Unfortunately that appears to add to the vertical space significantly, which when you have multiple partitions becomes very difficult to manage due to bug 507933. The ideal would be to have an inline sensor.
Comment 5 alkalinelemon98 2025-08-10 23:34:34 UTC
That makes sense. Having the total space sensor set in the way i mentioned would exacerbate the other bug (its kind of a feature too) even more, and it would also just take up ridiculous amounts of vertical space in general.

As you said, being able to show the results of the used and total space sensor in one line would be ideal. I did spend a bit of time reading through the source code of System Monitor but I still don't really understand the app's architecture enough to add this little thing.

If i do figure something out then I will make a PR for sure.
