Gurus please help

[shorty]

I have about i have a folder with about 30 sub folders in it that i need to place into my outlook inbox pane
Example: i have a .pst that's names "States" in this file is 4 different state.

Now each of those state folders will need about 20-50 sub folders.
Is there a way for me to create a batch of folders to put in, or will i have to make each one, 1 by 1.
I have created another folder on my desktop with all of the sub folders already there, i tried to just drag and drop them into the state folder, but i get a error message.
