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 an OTP file?
The OTP (OpenDocument Presentation Template) format is an XML-based standard for presentation templates, maintained by the OASIS consortium and defined in the ISO/IEC 26300 specification. It utilizes ZIP compression to package XML manifests, styles, and multimedia assets into a single container. Unlike proprietary binary formats, OTP enforces strict open standards, ensuring interoperability across different software suites while storing layout master slides and styles for reusable presentation designs.
How to open an OTP file
OTP files are natively supported by open-source office suites adhering to the OpenDocument standard. Linux distributions often include LibreOffice Impress or Apache OpenOffice, which open these templates by default. On Windows and macOS, users can utilize Microsoft PowerPoint (version 2007 SP2 and later) or Corel WordPerfect Office, though LibreOffice remains the reference implementation for maximum rendering fidelity.
