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.

What is a POTM file?

The POTM format is a macro-enabled presentation template introduced with Microsoft Office 2007, adhering to the Office Open XML (OOXML) standard. It utilizes ZIP compression to organize XML components but, unlike standard POTX files, allows the storage of Visual Basic for Applications (VBA) code within a vbaProject.bin part. This distinction enables the automation of tasks and custom scripting within the template structure.

How to open a POTM file

Opening POTM files requires software capable of executing or suppressing VBA macros securely. Microsoft PowerPoint is the primary application for Windows and macOS. While LibreOffice Impress and WPS Office can open the slide content, macro execution may be restricted or unsupported due to differences in the scripting backend compared to the Microsoft VBA engine.
