Thank you Leszek,
I tried df -h which also tells there is very little space. Installed kdiskfree, which I think gives the same information.
ncdu is really nice for checking what is using space. Happy to know this simple program exists!
However I don't see what ate the 45Gb Could something be wrong with the drive?
One thing it tells about the home/user1 directory: "Total disk usage: 280.7 GiB Apparent size: 287.2 GiB Items: 83490"
7Gb difference, not sure what it is though it's much smaller than the total missing amount.
That said about the root directory it tells:
--- / -----------------------------------------------------------------------------------------------------
. 388.3 GiB [##########] /home
. 34.9 GiB [ ] /var
5.9 GiB [ ] /usr
887.6 MiB [ ] /lib
351.5 MiB [ ] /opt
178.6 MiB [ ] /boot
etc
etc
"Total disk usage: 430.6 GiB Apparent size: 430.6 GiB Items: 765432" Usage and apparent usage the same
(home includes a second user which makes up the difference in the home directory)
However the partition manager reports /dev/sda2 size as 463 and used 430, so it seems there is 33Gb available. Then why is the system thinking there is just 2.3Gb (what I freed up later)? Why would the trash folder still report 45Gb and any other folder selected in Dolphin 2.3Gb?? And why could it suddenly disappear?
