Hi I have installed Windows XP SP2. I'm not able to compress or compact virtual hard disk; the messages sond like: " ... because the virtual machine has Undo Disks option enabled or the hard disk is used in snapshots ... " The Undo Disks is DISABLED, and I have create and DELETE all snapshots! I also have deleted Snapshots.xml file and Snapshots dirctory, but nothing ! Within Windows the C: disk is 8GB, but on Mac the virtual machine is 15 GB !!!
