my desktop has 2 hard drives. first is a 10gb (original) the other is a 120 gb (added later). first is partitioned as 6+ and 3 (C & D). I'm running tight on C and would like to remove D and increase the size of C to 10 GB. Can I do this without buying another program or unloading, reformatting and starting over? The info on D is no longer usefull.
