Description Jakob Erzar 2020-11-17 20:52:40 UTC

The amount of available space for a partition does not match the amount of space that is shown by the command df. This is mostly because df accounts for the reserved blocks, whereas Filelight does not. 
Since the reserved blocks usually cannot be used by the user running the program, I think the behavior of Filelight should be changed. This would also make Filelight more consistent with Dolphin, which shows the same amount of free space as df.

STEPS TO REPRODUCE
1. Run df -h and observe the amount of available space on an EXT4 filesystem partition
2. Open Filelight and hover the same partition to see the amount of free space

OBSERVED RESULT
The amount of free space is different between the two programs.

EXPECTED RESULT
The amount of free space should be roughly the same between the two programs.
