Parallels 8 / windows XP - can't convert from expanding to fix disk I'm running out of disk space on my macbook air, and noticed that my Parallels hdd file is 48GB even though the XP disk is only 28 GB. Inside the .hdd file there seems to be a number of ".hds" files. The parallels disk is configured as an "expanding disk". I'm basically trying to work out a way of getting the extra 20G back. I tried to convert the expanding disk to a fixed disk, but when I tried to uncheck the expanding disk option, I got a "Unable to edit the hard disk properties because it has one or more snapshots" message even though I don't have any snapshots. Does anyone know a way around this problem?
