I have a small hard drive in my linux box, and I am trying to get a few thigns working. I know I can delete the *.tar.gz that I have downloaded, but what about the directory made after I untar it? Is that okay to delete, or is it still somehow needed for the whatever program it was? Also on a side note, I am curious as to how to uninstall something that I have already installed. If it is long don't worry about it, but if you have time, or it is short that would be cool.
