>>PMFJI, do you know if SMB affects VFP converting XML file to a DBF? Or it is only when VFP application opens DBF/FTP files?

>I don't see how would that matter. SMB is about filesystem, so file control blocks, handles, locks at the raw bunch-of-bytes-on-disk level. File types don't even exist at that level, file types are for launching apps or for apps to decide what to do with them.

Not so sure I follow your argument. SMB protocol could be viewed´/interpreted as a LAN based interface into the server file system. Server settings like Oplocks/Caching may throw a wrench into expected operations.

might not be the problem, but specific file type usage (as in ISAM)
