That's a real catch-22 there -- I can't detect the mapped drive to get the UNC and only the UNC will work, eh? Thanks for the explanation, though.

Question #1: If I use the 'Validate Path' string function on the mapped drive, it appears to work (returns the same path with the mapped drive.) How does that work when other mapped drive type functions fail?

Question #2: Can I trap the "Target directory not writable or accessible" error so that I can handle the situation gracefully?
