Thanks Malaire! That was very helpful, I will try that command. That is exactly the information I was looking for. I have filelight on my 5.0.1 CD and I've been trying to understand it, but I just don't seem to follow the concept behind the diagrams. Anyhow, I've ordered the DVD version and hopefully there will be some help content on that. The CD doesn't really have any help files at all, that I've been able to find. I'm a complete kn00b with this stuff, but I am hoping the CD will help me understand enough to know which Linux I will want to install on the secondary HDD in my Windows XP box.
