The explanation is that FoxPro 2.x was written before UNC existed, and doesn't know about it. As far as FoxPro 2.x knows, \\server\share is an invalid path.

Similarly, as far as FoxPro 2.x knows, longfilename.ext is an invalid filename. Although in the case of the long file name, FoxPro 'conveniently' 'fixes' the file name for you, and looks for longfile.ext instead, and probably gives you a file not found error instead of 'invalid file name'.

One of the reasons to recommend for your clients to upgrade their systems to Visual FoxPro.

HTH,
