 Dragging a folder from Windows Explorer to Project Navigator 
Note: If the folder you are dragging onto the Project Navigator palette contains drawing (DWG) files, you are prompted to add each one as a project file. For example, if you drag a folder into the Elements category in the Drawing Explorer, the Add Element dialog box displays prompting you to add each DWG file within that folder as an element.
