Hello,
the displayed amount of disk space used in the KDE partitioning tool and in the file browser is too high. It shows that 840 GiB of 914 GiB of my SSD are used, but when checking the actual file size (for example in filelight) all of my data beginning from / is 438 GiB. I noticed a couple days back that more disk space is used than it should be, but now I am worried what happens when my SSD "has no space left". After further investigation I noticed, that the baloo_file_extractor uses some disk I/O, but that never gave me trouble in the past. I am really lost here and don't have a clue on what to do. Any help would be greatly appreciated.

Check how much space your logs and your package cache is taking up. Delete them if you need to reclaim space. Delete all your timeshift snapshots, then perform a btrfs balance.

I already deleted the logs and the package cache, but that was of no help. I did a btrfs balance, but did not delete the snapshots beforehand. I will try that next, thank you.

So deleting the snapshots from timeshift did solve the problem, although I don't know why they suddenly became a problem.

Even simply deleting the snapshots sometimes is not enough to reclaim the used space. Be sure to perform another btrfs balance after deleting all timeshift snapshots and that should fully reclaim the lost space.
Glad to hear that helped.
