Information is power, and within PowerPoint 2010 all the information that you need about your presentation is available in a single convenient location. This is the new Info panel of the Backstage View. This panel gives you information about permissions set for the active presentation, helps you prepare your content for sharing, and also lets you recover older versions of unsaved files. In addition, it also provides access to all the properties for a specific presentation. To access the Info panel, open the File menu, and choose the Info option.
