And if you deleted the files in a GUI then they're probably still
lurking in the Trash somewhere.

Also, the system reserves 5% of the disk for files owned by root. This
is to ensure that if the disk fills there's still a little bit free that
the system can use (useful on the root filesystem, not so useful on the
home filesystem). It's possible that if you were really close to being
full and the files you deleted were owned by root then you won't see the
space free up because you're just clearing out the reserved space. Try
turning off the reservation with `tune2fs -m 0 /dev/fedora_laptop/home`
and see if that frees up some space.

Shane.

I did, moved them to the wastebasket then deleted them form it. The GUI
showed it as empty BUT I am not convinced as it used to showed a
progress bar for large files like my old iso's which I did not see and
it deleted the files very quickly!!

I just deleted another 800MB iso, deleted it from the wastebasket,
switched off and rebooted, LVM shows no changes. I also think they are
still somewhere on the disk.
but did a:
find . -type f -name '*.iso'
and they do not seem to be there.

I will bring it to the KT if I don't sort it by Saturday in case there
is an "expert" who want a free drink!

The big files were owned by me so I thought should have given up space.

Hi Ron

Sadly all the PCBs are full height. You couldn't even crop down the
metal back-plate.
