The big change in PowerPoint 2007 was that the stable binary file format of 97-2003 (.ppt files) was replaced as the default by a new zipped XML-based Office Open XML format (.pptx files). Microsoft's explanation of the benefits of the change included: smaller file sizes, up to 75% smaller than comparable binary documents; security, through being able to identify and exclude executable macros and personal data; less chance to be corrupted than binary formats; and easier interoperability for exchanging data among Microsoft and other business applications, all while maintaining backward compatibility. Here are main presentation formats supported:
- Microsoft Office PowerPoint presentation format.
- Old Microsoft PowerPoint 97-2003 binary presentation.
- The Open Document Format for Office Applications (ODF).
