Hard drive full when not full?

My hdd holds 72gigs, but I downloaded a movie that took up the rest on it and when I went to delete the movie it wont let me. Also tried to remove programs that were over 1gb and they were removed, but my hdd still says free space:0MB. I have deleted over 5gbs of programs and still no change even after restarting winsxp many times. I ran hijackthis and would like someone to look through it and tell me any files that I could remove. Thanks in advance!
