Questions & Answers
PPSX documents: Frequently Asked Questions
What are PPSX files?
PPSX is the Office Open XML slide show format of PowerPoint, which has the same content as a PPTX file and differs in the way that it is launched. It is a ZIP package with XML parts for the slides, the layouts, the master, the theme, the animations and transitions, the notes, and the media files, and when the user double-clicks it, PowerPoint starts the Slide Show view directly and not the editor. The show ends and closes the program when the last slide is passed, or when the user presses the Escape key. The file is editable: it can be opened through the File menu of PowerPoint, or saved as a PPTX presentation, and the PPSX extension can be changed to PPTX, with the same result. The format cannot hold macros, and a slide show with macros uses PPSM instead. The older binary slide show has the .pps extension. Supported by Microsoft PowerPoint.
