Yea, I know exactly how to do it, it just in fact will not let me do it. I have attached some images as proof. If you try to delete any of the 3 small partitions the only right click option shown to you is "Help" and the C & D partitions can only shrink, no Extend. I've deleted D before and C still couldn't extend because of the one partition in between that I can't delete. Maybe there's a program that can override this limitation.
