I'm trying to download a small file. I get this message:

"There is not enough room on the disk to save /tmp/F2OOgu26.deb.part.

Remove unnecessary files from the disk and try again, or try saving in a different location."

It seems that my "/" has grown to almost 30 gig in just a few weeks.

Any suggestions as to where I can start looking to delete files in "/" to free up some space?

"/" is 30 gig
/home is 60 gig.

Thanks!
