I have come to the stage where I'm getting a message that my Back-Up drive is nearly full. What I'd like to do is browse the archives, so as to delete some of them. I want to keep the first back-up and a couple after the installation of certain programes, but I don't need all the others as they are all full back-ups. I think in future the way to go is an incremental back-up, so only backing up the changes. Can someone help me here, I can see all the back-ups but I don't want to find I have deleted something that will render the other back-ups un-useable.
