If you are a large team of executives or consultants, it is likely that very often all of you have to work together on one presentation. With Internet and social media, it has become very simple to share and download presentations, making it possible for your team to work virtually. Every member of the team can make their own changes in a presentation and share it with the others. So how do the other team members know what changes were made and how can the members compare PowerPoint presentations? We all have heard about track changes in MS Word where the user can easily view the changes that have been made by another user.
A recent article in How to Geek explains how users can easily compare different versions of a slide deck.
With this feature, you can easily see what changes that have been made to your original file. When you want to compare two presentations, Open the Original file (presentation)>Click Review>Click Compare.
You can see a detailed video here.
This feature is available only with PowerPoint 2010.
