>What does the DIR() function return if you pass it a string for a directory that doesn't exist? The help file wasn't very "helpful" with this scenario.

If the folder exist, the name of a file (contained in this folder) will be returned. If the folder doesn't exist, Dir returns an empty string (an empty string is also returned if the folder exist and has no file in it).

You could also try the ChDir function which will return a run-time error 76 if the folder does not exist.
