There you go, listen to Lee; he likes to talk more than I do.
Hey? What? I thought I was listening you too. Sooooorrrrrrreeeeeee!
I got it working with car function. It took me a little bit of trial and error. I can not say that Autodesk help files are of much help on this subject. But then I realize that vl-directory-files is the right function.
I think vl-file-copy might be better suited when it comes to my users. I am not sure, I will have to look into it some more.
