.PPSM File Extension

Microsoft Office PowerPoint (2007+) Show (Macro Enabled)

Plugin File
Files with the PPSM extension indicate a slideshow created with Microsoft PowerPoint, versions 2007 or later. PowerPoint was developed by Microsoft and is currently the leading application for creating, editing and showcasing commercial and non-commercial presentations. It is available for both Windows and Mac OS.

PPSM files contain individual pages known as "slides" which are fully customizable. These may contain text, pictures, videos, graphics and other objects that can be arranged freely within the page. The PPSM format was created mainly to ease the sharing and distribution of PowerPoint presentations. Besides PowerPoint, PPSM files can also be opened with the lightweight Microsoft PowerPoint Viewer application which is free. However, once a PPSM file is saved, it cannot be edited with this type of applications.

Additionally, the PPSM format may contain Macros which can save command sequences and replicate them automatically. The standard format for saving PowerPoint slideshows is PPSX and it can also include macros. However, PowerPoint won't execute them until the file is saved as PPSM.

The PPSM format is based on the Open XML architecture which stores all content in a zipped archive. The archive contains XML, RELS and media files (if applicable) stored in three separate folders named “docProps”, “ppt” and "_rels". Files with the RELS extension dictate how the parts of the document connect to form a single file. This archived approach makes file content more accessible. For example images and text are stored individually within the archive.

How to open PPSM files

The contents of a PPSM file can be extracted individually by opening it with a data compression application (i.e. WinZip or WinRAR). The XML files of a PPSM document can be opened with any basic text editor and any web browser.

PPSM files can be viewed with the following applications.
