A .pptm extension file is a macro enabled open XML, Microsoft PowerPoint Presentation file. The presentation pages that are termed as slides comprise of text, images, videos, graphs and other components including media files that are required in a presentation. This feature is especially helpful to create presentations for the academic, marketing and business domains where a large amount of content needs to be stored. The advantage of using the .pptm extension as compared to .pptx is that macros can be executed in files with this extension whereas it is not possible to execute macros in .pptx files even if it has macros in it, apart from that both formats have similar features. Microsoft introduced the Open XML format for PowerPoint presentations in 2007 hence files with this extension cannot be opened with previous PowerPoint versions. However, if a Microsoft Compatibility Pack is installed along with the previous versions, it would be possible to open the files with .pptm extension.
The PPT format is a proprietary binary file format developed by Microsoft. It is mostly associated with Microsoft office PowerPoint, a closed source slide show presentation application. In Microsoft PowerPoint 2007 onwards, the .ppt filename extension format was superseded by the .pptx format which is part of the Office Open XML specification. Documents to be saved in the .ppt format are saved as PowerPoint 97, 2003 presentations.

PPTM files can be converted to other formats that include PPT, PDF, PNG, PPTX or JPG. It can also be converted to a video format like MP4 or WMV. The recent additions to the presentations include features like inserting music that plays all through the presentation, sound effects to highlight specific slides, designing the presentation to play on its own just like a movie, recording the slide show with a pointer on one hand and narration on the other, repetition and shuffling the order of the slides as per requirement.
The ppt format uses Microsoft's OLE 2 compound document file format. It contains a hierarchical structure of storage and streams broken down to a user stream, PowerPoint document stream, pictures stream, an optional stream, and custom XML data stream. Actual content is represented as slide containers within the document stream. The format allows the inclusion of external objects such as pictures, sounds, and movies into one presentation.
