I find Explorer extremely limited as a file manager, in part because it lacks two facing windows, which I think is what you're trying to set up.
As an Explorer replacement, I use Total Commander from ghisler.com. It's a Windows version of the old Norton Commander, which I used from the first with MS-DOS, so I know it in my sleep. Extremely easy to duplicate a window, among other things. Can't recommend it too highly.
