Microsoft PowerPoint creates PPSX files to save presentations in a format that allows users to more easily view a slide show. When users double-click the file, it opens directly as a slide show presentation instead of a working slide show, like a .PPTX file. The files were introduced with the release of Microsoft PowerPoint 2007, replacing PPS files as the default PowerPoint slide show format.

PPSX files may be used to store various types of presentations, including seminars, reports, or photo slideshows. You may receive PPSX files attached to emails from co-workers or friends looking to share slide shows. You can use File Viewer Plus to view PPSX slide shows or convert them to JPEG, PNG, or PDF format.
