When I try to open an AutoCAD file, I got a command says 'Enter name of drawing to epen <.>: ---- What is the key stroke or option to turn this command off. I forgot.Thank you. 

set FILEDIA to 1

Whenever that happens to me it usually means that the file does not exist or is not valid to the CAD version I am using....if that helps, even though that is not a good thing, but it has happened to me in those cases. That is the only time I have seen that happen, either the path to the file is lost or something. CAD should not show a message like that when trying to just simply open a CAD file.

Thank you. I got it!
