The PPSM format is used by the Microsoft Power Point presentation software. PPSM files are used to store complete presentations made in the program. PPTX files are often used for this purpose, but PPSM files also support macros defined in them. PPSM files are based on the Open XML format. They are compressed using the ZIP format.

Microsoft Power Point is a component of the Microsoft Office suite. PPSM files have been used by the application since version 2007.
