Compare and Merge Presentations in PowerPoint 2010

Sometimes you need to compare two PowerPoint presentations to see what were the changes introduced by your companions or co-workers. Even clients may introduce modifications that you should check before starting with a project and the Review features in PowerPoint 2010 can help you to do this work and make it easier. The natural way to compare both files is to go slide to slide comparing and trying to identify the changes. You not only need to see what was changed but also pay attention what was added or removed from the presentation. This can be strenuous and boring task. However, the Compare button in PowerPoint allows you to become an expert in proof reading PowerPoint presentations and detecting visual differences.

To illustrate how to use Review in PowerPoint we will compare a presentation on Social Media that was created for a client.
