| Description | PPTM is a file format used for PowerPoint presentations that contain macros. It was introduced by Microsoft in 2007 as part of the Office Open XML (OOXML) specification. The PPTM format is similar to the PPTX format, which is also used for PowerPoint presentations, but with the addition of macro support. |
| Technical details | PPTM files are saved in a compressed package format, which is based on the ZIP file format. They contain a collection of XML files that describe the presentation's content, formatting, and macros. The macros in PPTM files can be written in Visual Basic for Applications (VBA) and are used to automate tasks and add interactivity to the presentation. PPTM files can be created and edited using Microsoft PowerPoint, as well as other presentation software that supports the OOXML specification. To run macros in a PPTM file, the user must have macro security enabled in their PowerPoint settings. This is because macros can potentially be used to execute harmful code on a user's computer if they are not trusted. |
