Yesterday I had 58gb left on my hard drive. Today it is down to 56. Now I know I use memory intensive programs (creative suite and making very large ps files eg 1gb) but I'm pretty sure I haven't added 2gb worth of work in a day. Is there hidden files (like the old "temp" files on OS9 or printing files) that I don't know about and need to delete? Tried to have a look at the Activity Monitor but it won't launch - there is no preference for it and the console gives me a "tool is not setuid root - please repair the privileges" message. I have a G5 1.6GHz, OS 10.3.3, 2 x 80gb hard drives running 1.25ram. At this rate I will run out of hard disk space in a month!
