Pauline, using a program like Partition Magic you would be able to resize your partitions to increase the C: partition and reduce the D: partition to suit. This is assuming you are referring to "Partitions" in your letter and not "Hard Drives". Regards Alan Priol Not sure if I am asking the right question about my problem. But I will give it a try anyway. I do not know alot about Comp. But here goes. I have two hardrives C & D. My C is the one I always use. It is Full, What do I have to do to make my D the primary It is twice the size of my Cdrive. Please tell me where to go or do I need to hire an expert.
