About PPSX
PPSX
PPSX is a Microsoft PowerPoint Slide Show format that opens directly in slide-show (read-only presentation) mode rather than editing mode. PPSX is structured identically to PPTX, but the .ppsx extension signals that the file is intended to be displayed, not edited. PPSX is used for distributing finished PowerPoint presentations.
