The easiest way to see which directories are taking up the most space is to run this command, from your home directory:

du -hs *

Then, 'cd' into the directory that is taking up the most space and run the same command again.

Repeat the process until you find the files that are actually taking up the space.

Another command that is useful is "ls -lh", which shows how much space the files in the current directory are using.
