Your return line ought to be drive&":\" I think, but you're returning 
after checking the letter C, there should be a test there to see if 
the file opened ok.

You don't have to use an Xtra to do this job. getNthFileNameInFolder 
would do the job just as well. You would check to see what the name 
of the first file in the folder driveletter&":\testfolder\" was. If 
it's "", then that's not the right drive letter.

I would think about working through the alphabet backwards, because 
on some Windows systems you can run into trouble if you have a Zip 
drive that doesn't have a Zip disk in it at the time, and the Zip 
drive letter is likely to be earlier than your CD-ROM drive letter.
