I have a Sony Vaio with a 120 gig C/D drive. The C drive only has 13 gigs for programs, etc. D is full but I can move stuff over to a 300 gig Maxtor external. The problem is, there's nothing to delete on C and I'm at times under 99 mb of free space. I need to make the partition like 25 gigs or more. How do I do this without having to save everything to disk?
