How to merge the two network drives?

I got this MyWorldBook drive setup on my computer, and when I open Computer (Windows 7) it shows two drives, Public and download, both are the same drive. That’s really annoying to me and a waste of space, so is there any way to just merge the two so it’s just one drive? I hate the extra navigation and extra annoying choice to decide which one to save stuff to, so how do I merge them? Also when you tell me how to merge the two drives (if there is even a way to do it at all) should I back up the data that is already on there before I merge them?

Sorry you cannot merge the 2 default folders. you can create your own if you would like.
