Linking a Diagram to a Microsoft Office Document
When you link a Visio 2007 diagram to a document in an Office application, the document file stores a reference to the original diagram. If you edit the diagram—either in Visio 2007 or within the document—the diagram changes in both places. And if you’ve linked the diagram to more than one document, each of those documents will be updated. Because each of these documents is linked to a single Visio 2007 diagram, your documents stay smaller, which means you can work in the documents more quickly and they take up less space on your hard disk. However, any time you need to use the Office document that contains the link, the original Visio 2007 diagram must be available in its original location.
