>>>You see, on my computer when I use a mapped drive (just like you did, e.g. 'd:\data\somefolder\') everything works. It is when on customer site and they use a UNC (e.g. '\\servername\appname\data\') the program (GetFile()) has a problem.

>I am back to your suggestion of 'fullpath()'. It didn't make a change as to where (folder) the Open Dialog of getfile() fires. But I was wondering about a different aspect of it. I tested the return from getfile() with and without enclosing with fullpath(). And in either case the GetFile returned the file name with full path (e.g. "c:\appl_name\data\file_folder\file.pdf"). How should FULLPATH() make the difference?

Lesson #1: Never trust your memory. This case proves why this rule is so important. I didn't remember that getfile() in deed returns the complete path, so it's redundant in this case.
