In PowerPoint, all information that you need about your currently active presentation is available in a single easily accessible location. This location is the Info pane of Backstage View. Using the options available within this pane, you can access information about permissions set for the active presentation, prepare your content for sharing, and also possibly recover older versions of unsaved files. In addition, the Info pane also provides access to many more properties.
To learn more, choose your version of PowerPoint. If we do not have a tutorial for your version of PowerPoint, explore the version closest to the one you use.
