pps A .pps extension file is a PowerPoint Show designed with the help of Microsoft PowerPoint application. This file consists of text, audio-visual components, animations, images and hyperlinks that are combined as required to present a slide show to a group of audience. It is particularly useful to present slide shows for the educational sector and for corporate presentations but can also be used for personal presentations. Interactive and dynamic multimedia slide shows are created with the PPS format. The .pps file extension is similar to .ppt extension files except that the presentation directly opens in the slide show mode instead of the edit mode. Files saved with the .pps extension cannot be edited as they are converted to the slide show format. They are smaller in size than the PPT presentations and can be sent across from one user or device much faster than the presentations with .ppt extensions.
