If you are working on a presentation with your clients, or even a co-worker — then you might end up in a situation where you both did not work on the same copy, one after the other. Instead, you worked on two different copies. These copies contain changes done by you both — some similar and some different. Now you need to compare and merge these copies into a single, cohesive file without losing anything at all! Yes, you can manually compare side by side in PowerPoint 2013 — this option works great if there are very few changes. For anything more involved, you will want to use the Compare feature which was introduced in PowerPoint 2010 for Windows. This feature combines two presentations provided by you, and then shows you the differences between them. You can then decide which changes to include, or discard within the final version of your presentation.
