Yes, Narsil, I did that too-- is there any optimum number, I just picked 100. And now I have access to the space. My disk cleaner regularly clears my temp files. And, yeah, SamTherapy, I mentioned 16G because it seemed to be the limit. Very sad indeed. It can't actually be using 16Gs to render. I think Windows only allows it 4Gs. But if it drops below that 16, get out the cd burner, start moving files. Emily
