The file extension .pps is associated with the formats POT, PPT, and PPTX, which can all be created with the Microsoft PowerPoint program included in the Microsoft Office productivity suite. Microsoft also provides a free PowerPoint Viewer that can be downloaded from their web site, and it is intended for systems that do not have an installed application that can handle presentations.

Cannot open pps files in Windows?

Not being able to open pps files in Windows may be a result of registry errors or not having the appropriate application installed. It is strongly recommended that you scan your computer for registry errors (free).

However, creating or editing the .pps file extension requires the presence of the actual presentation software application like Microsoft Office PowerPoint. Moreover, the appearance of third party software applications capable of interpreting .pps file extensions have contributed to the widespread usage of the format file. The deployment of the file extension .pps ensures the continued usage of dynamic, high impact, and integrated presentations as a way of sharing information.
