What is a PPSX file?

A PPSX file is a slide show created by Microsoft PowerPoint or another presentation program, such as OpenOffice Impress or SoftOffice Presentations. It contains a finished collection of slides that are used for slide show playback. PPSX files are similar to .PPTX files but open as a presentation slide show when double-clicked, instead of a working presentation file.

PPSX file open in Microsoft PowerPoint 2019

PPSX files are useful for sending finished presentations to users that just need to view the presentation instead of editing it. However, they can still be edited in PowerPoint but must be opened directly in the program by selecting File → Open and choosing the PPSX file.

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.

NOTE: Even though OpenOffice.org does not natively open PPSX files, you can still open them in the software by selecting the "Microsoft PowerPoint 2007 XML" option from the list of supported file formats.
