.PPTM File Extension
File TypePowerPoint Open XML Macro-Enabled Presentation
What is a PPTM file?
Macro-enabled presentation created by Microsoft PowerPoint, a program used to create presentations and slide shows; contains a collection of slides, including their text, layout, images, and embedded macros; commonly used to store business, marketing, and academic presentation materials.
Unlike .PPTX files, PPTM files may execute embedded macros. Even if a PPTX file includes macros, PowerPoint will not allow users to run them. They must first be saved as a PPTM file, and then the macros may be executed.
PPTM files are based on the Open XML document format, which was introduced in Microsoft Office 2007. They may be opened in PowerPoint 2007 or later, or by previous versions of PowerPoint with the Open XML component installed.
