I am using Parallels and using it with the expanding hard drive option. The hard drive is set up for 32 gigs. In the Parallels screen it shows I"m only using 19 gigs. When I go into Windows XP it shows 11 gigs used, 20 gigs free. I'm not sure of the reason for the difference but either way I don't plan to install anymore software and possibly uninstall some from Windows. Is there any way I can change the size of this virtual hard drive to make it smaller? I tried using the compact option but it didn't make any difference.
