The puzzling thing is that sometimes it works, & sometimes not.

The path is "\\tswsbs1\user data\bobe\my documents\proteus\proteus\da current feedback\finished programs\1200 settings.bas" which is 103 characters.

Also it worked every time in windows 2k pro, which i was using until monday.

Oh well some things just remain a mystery. At least I can move files to my c drive while working on them, and move them back to the server once complete.

Thanks for all your help guys
Regards
Bob...
