I am running vista 64 and want to add more space to my os partition. I have my hdd partitioned to dual boot XP(which I don't really use anymore) and Vista Ultimate 64 bit. I then have documents etc on the other partition with about another 400GB of space left. I have had to add some more things to my vista os and with sp1 and sp2 coming out shortly I would like to add some more of my unused space to it. What programs do people use for vista on this? Thanks.
