I just opened filelight; it is fasinating.  Some areas occupy as much as 
6gb of data, but how do I learn what is relevant and needs to be kept 
and what is either no longer needed or redundant or saved for purposes I 
do not require?  When I google something like, /var, I get a rather 
basic understanding of what it is, but whether it is necessary to the 
continued function of the computer is not mentioned.  I don't even know 
what temporary files should be retained; can they all be removed, or by 
having them do they save time when you may need  them again?

After reading the function of /var files, it looked to me like they 
should all be kept, if you have sufficient space.  The key being whether 
you will use them again or often, I guess.

When people start making decisions about what to keep or what to get rid 
of, what are some examples of how such decisions are made?  Or is there 
a tutorial for that; and what would I google to find it?  It seems to me 
like I have very important and busy people doing work I should do for 
myself.  It would be nice if there was a guide for we beginners that 
would direct such a path as the questions start coming.  I hate to waste 
other people's time.
