About PPSX Files
A PPSX file is a PowerPoint presentation saved so it starts playing as a full-screen slide show as soon as you open it, instead of opening in the editor. The content is the same as a PPTX. The older version of this format uses the .pps extension. To edit a PPSX, open it from inside PowerPoint with File, Open, or simply rename a copy to .pptx.
