I installed parallels with windows XP about a month ago; thereafter I installed(in windows XP) a lot of programs, but ended up deleting everyone of them, then something shocking occured. Parallels occupied a wooping 10GIG on my mac harddrive. It was only around 1.8Gig when XP was first installed with no additional programs. But I uninstalled and deteted every windows program in the end so there is no reason for parallels to still take up 10Gigs!! Can someone explain this?
