Have parallels 6.0 installed, and Win XP, on a Mac OSX v10.7.2. The 2 monster files are: /Users/Dave/Documents/Parallels/Microsoft Windows XP 1/winxp.hdd ----> (37 GB) /Users/Dave/Documents/Parallels/Microsoft Windows XP 1 (1).pvm ----> (45 GB) Is there anything I can do (within reason) to reduce the amount of disk space required for this setup? TIA
