That's where we'll have to agree to disagree Gareee, my runtime is bigger than the OP, coming in at 13 Gig and I don't have a speed issue with a single runtime, the initial start up takes a couple of minutes but the application doesn't give me any problems and the way I have it sectioned with sub folders and sub folders of sub folders, works really well for me!

Couldn't have said it better!
