Newbie Q - copying a directory structure and renaming

HI,

I've been playing around for a couple of days now creating userforms and simple stuff like that to speed up data entry at work.

What I am trying to do is copy a directory structure and then rename it so the root reflects a particular project (e.g. DS0213, DS0214 etc etc) with the DS bit prompted by a textbox in the userform.

I've come accross CopyDir and MkDir but how do I program in the user variable bit?

Any help appreciated

Thanks
