There are several ways you can open project files (.MPJ files). If you are opening a project created in RoboHELP 7.00 (released in 1998) or an earlier version, see Before you open existing projects.
Tip: If you need to track down a file or project that you are unable to locate, you can view a history of files that were open in the program. From the Tools menu, select Options, and then click the General tab. The Most Recently Used Files List displays the names of the projects and files recently opened in the program, including their drive/folder locations.
