You can add two kinds of references to presentations:
Document–When you add documents directly to a presentation, a reference to a unique document identifier is created in the presentation. Wherever the document is moved, the presentation can locate and present the document.
Folders–When you add folders to a presentation, the folder reference is directly added to Presentation Content, but documents in the folder are dynamically referenced. Documents added or removed from the folder are automatically added or removed from presentations referencing that folder.
Note: | You cannot dynamically include descendant folders, or presentations in target presentations. When adding a folder to a presentation, only documents immediately in the selected folder are dynamically added to the target presentation. |
