For the content, there are three options available:

§ Filename: Link to a file that needs to be available at print time.

§ Embedded: You select the object type via the standard Windows dialog "Insert Object". Here you can choose an existing file ("Create from File") or create a new file. The object will be embedded in the project. This can be useful e.g. for simple drawings or rather static objects.

§ Formula: Allows a formula for the file name.
