Diff for Powerpoint

Question

In Word, there is an option to compare two documents and find out the differences between the two documents. I'm looking for a similar function to compare two Powerpoint documents. Ideally, it would list the individual slides that are different, the differences in each slide between the versions and when the changes were made. However, I can't find a menu option for this functionality (I'm using Office 2007). Am I missing something?

If this functionality is not in Powerpoint, are there 3rd party tools doing this?

First hit on Google for "Powerpoint diff":

Answer 2

Failing all else, if you have Office 2007 you can always save the ppt as an OOXML document.

Answer 3

Apparently there was some functionality in PowerPoint 2003 to compare two PowerPoint files, but as I don't have access to a working installation, I can't really tell about the functionality of the compare. As Ben has noted, you can find a number of 3rd party tools doing a diff.

This feature has been discontinued in Office 2007. As far as I can tell from the documentation, there is some integration with SharePoint that should be used, but the whole concept is very differnt from a presentation diff. The way I understand it, you can version individual slides (with get and commit type of functionality), create new presentations from existing slides and be notified when a slide you are using is changed by another user and committed to the repository.
