I have Windows and Linux on my computer (256G) and Windows has C: System(65G) and D: Data(65G), my Linux has /(108G) and System, Data are also mounted on /.
df -h

I want to check the size of / without /System and /Data, and the Dolphin says it has 128TB:
It seems that it will show 128TB because it cannot know the size of /root and /lost+found?
