set framesetpath=d1 [:dn]

This command specifies a list of directories to search for framesets. Specify each directory separated by a semicolon. A list of multiple directories must be enclosed in quotation marks.

If there is an Arbortext-path\custom\framesets subdirectory at startup, the \custom\framesets path is automatically prepended to the frameset path. Putting your framesets in the \custom\framesets subdirectory makes them automatically available, avoiding manual steps to add them to the path.

You can use the append_frameset_path function to update the frameset path.
