I'm working in Visio 2000 to change some drawings that were created in an earlier version of Visio. When I try to edit the text of a graphic object, I get the error message "C:VisioDrawings is not accessible. The folder was moved or removed."

The graphic is stored at another (network) location. Is "C:VisioDrawings" some kind of default Visio path or could it be a path that was used by an earlier writer?
