What is a PPSM file?
The PPSM (PowerPoint Macro-Enabled Slide Show) file format is a presentation file type developed by Microsoft, based on the Office Open XML (OOXML) standard defined in ISO/IEC 29500. Unlike standard PPTM files, PPSM files are configured to open directly in slide show mode rather than edit mode. The structure utilizes a ZIP-compressed XML framework containing a vbaProject.bin binary part to store Visual Basic for Applications (VBA) macros, along with separate folders for slides, media assets, and relationship (.rels) files.
How to open a PPSM file
PPSM files are natively supported by Microsoft PowerPoint (2007 and later) on Windows and macOS, which executes the contained macros upon opening if security settings permit. For users without the full Microsoft Office suite, files can be viewed using the free PowerPoint Viewer or LibreOffice Impress. On mobile devices, the Microsoft PowerPoint app provides compatibility, though macro execution is generally restricted on iOS and Android platforms.

What is a POTX file?
The POTX file is the standard XML-based template format for Microsoft PowerPoint 2007 and later, standardized under ECMA-376 and ISO/IEC 29500. It uses ZIP compression to package XML data structures describing slide layouts, themes, and master slides. Unlike POTM, the POTX architecture strictly prohibits the inclusion of VBA macros, making it a safer alternative for distributing design standards without security risks.
How to open a POTX file
POTX files are the default template standard for modern presentation software. Microsoft PowerPoint provides full native support. Alternatively, users on non-Windows platforms can utilize Apple Keynote (macOS), Google Slides (web-based), or LibreOffice Impress, all of which accurately interpret the OOXML schema for editing and playback.
