The main differences between linked objects (linked object: An object that is created in a source file and inserted into a destination file, while maintaining a connection between the two files. The linked object in the destination file can be updated when the source file is updated.) and embedded objects (embedded object: Information (object) contained in a source file and inserted into a destination file. Once embedded, the object becomes part of the destination file. Changes you make to the embedded object are reflected in the destination file.) are where you store the data and how you update the data after you place it in the destination file (destination file: The file that a linked or embedded object is inserted into. The source file contains the information that is used to create the object. When you change information in a destination file, the information is not updated in the source file.).
What is a linked object?
When an object is linked, information is updated only if you modify the source file (source file: The file that contains information that was used to create a linked or embedded object. When you update the information in the source file, you can also update the linked object in the destination file.). Linked data is stored in the source file. The destination file stores only the location of the source file and displays a representation of the linked data. Use linked objects if file size is a consideration.
Note If the path name of a linked file exceeds 128 characters, Microsoft Office PowerPoint is not able to find and play that linked file. In such a case, you can either rename the linked file, or shorten the path name by copying the linked file into the folder where your presentation is located. Then either update links automatically by using the Package for CD feature, or update them manually by removing the sounds from the presentation and then adding them again.
What is an embedded object?
When an object is embedded, information in the destination file doesn't change if you modify the source file. Embedded objects become part of the destination file and, once inserted, are no longer part of the source file. Double-click the embedded object to open it in the source program (source program: The program used to create a linked object or embedded object. To edit the object, you must have the source program installed on your computer.).
