But we've already established that your CALSOD software can't access files over a network

but I'm not so sure about that. Remember: in DOS one likes (liked) to map drives consecutively (more or less) and there should be a statement in config.sys containing the 'highest' drive letter used. Edit: here I have (physical or virtual) DOS 5 or DOS 6 in mind, not an XP command line...

I'm not sure how that applies to a DOS application running under XP.
