Parallels 6.0 is using about twice the amount of disk space (120 GB) as required by my files. At one time I tried using the "snapshot" feature in Parallels which took up a lot of storage. Now that I use Time Machine and Time Capsule for backing up, there is no need for snapshots. I have since tried to delete the snapshots but Parellels won't let me saying the files are corrupt. In every other respect the Windows XP OS has been working fine. Parallels support has been less than helpful in solving this problem. I would really love to delete the snapshots. What are my options, if any, short of completely reinstalling my Windows operating system, apps and files? Because of this problem, I have been reluctant to upgrade to Parallels version 7 as it might simply import corrupted snapshot files into the new version of Parallels.
