What is this ppsx file?

Slide show created by Microsoft PowerPoint, a program used to create personal and professional presentations and slide shows; includes a finished collection of slides; used for saving finalized presentations and for slide show playback. Once saved, PPSX files cannot be edited and may only be viewed. Therefore, they are useful for sending finished presentations to users that do not own the commercial version of PowerPoint, since the PPSX file can be viewed with the free PowerPoint Viewer program. PPSX files are saved in the Open XML format, which was introduced in Microsoft Office 2007. They may be opened by PowerPoint 2007 or later, or by earlier versions of PowerPoint with the Open XML component installed.
