When I originally installed Parallels two years ago I went over board on the amount of Hard Drive space I allocated for it. I was under the impression that this number could not be changed without losing everything I have already in there. I can't afford to lose the data I already have and I don't have my copy of Windows anymore so a re-install is out of the question. Is there anyway to just go in and give back some of the HDD space to my Mac?
