| Description | The PPTM file format is used for PowerPoint presentations which include macros. Microsoft introduced this format in 2007 as part of the Office Open XML (OOXML) specifications. The PPTM format is akin to the PPTX format used for PowerPoint presentations, with the added functionality of supporting macros. |
| Technical details | PPTM files utilize a compressed package format, based on the ZIP file format, and comprise a cluster of XML files. These files represent the content, formatting, and macros of the presentation. The macros within PPTM files, which can be programmed in Visual Basic for Applications (VBA), are designed to automate specific tasks and enhance presentation interactivity. Microsoft PowerPoint is the primary tool for creating and editing PPTM files. For a user to execute macros in a PPTM file, they must enable macro security in their PowerPoint settings. This precaution is necessary due to the potential of untrusted macros executing harmful code on a user's computer. |
