So about this topic of Galaxy...

What was I talking about?

Linux is just as bad. I always wonder where the disk space on my synology server goes to. I don't have THAT much data on the primary volume.
Maintenance on a regular base is nececessary just as it is on Windows.

I had given up, sorry ladies/gents. However! I discovered where it was hiding. I had stopped Wasteland 3 half way through a download, to download something on another launcher. Half the game was dumped into my "other" folder on C:.

I was curious why I had so much in the folder and 22 of the 25 gigs was the game. Issue is resolved. I have no idea how I missed it before.

Definitely. Any computer device you own, be it a PC, a smartphone, maintenance and organisation is important. Regardless of the OS.

On Linux

df -h

and du -h --max-depth=(number)

are your friends.

df works from anywhere as it displays filesystems

for du you need to change to a directory first and it will display the disk usage for that directory and all sub-directories up to max-depth: change max-depth to 1 or 2 for best results.

baobab seems to be a similar program to spacesniffer for Linux desktop.
