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.

What is a PPSM file?
The PPSM (PowerPoint Macro-Enabled Slide Show) file format is a presentation file type developed by Microsoft, based on the Office Open XML (OOXML) standard defined in ISO/IEC 29500. Unlike standard PPTM files, PPSM files are configured to open directly in slide show mode rather than edit mode. The structure utilizes a ZIP-compressed XML framework containing a vbaProject.bin binary part to store Visual Basic for Applications (VBA) macros, along with separate folders for slides, media assets, and relationship (.rels) files.
How to open a PPSM file
PPSM files are natively supported by Microsoft PowerPoint (2007 and later) on Windows and macOS, which executes the contained macros upon opening if security settings permit. For users without the full Microsoft Office suite, files can be viewed using the free PowerPoint Viewer or LibreOffice Impress. On mobile devices, the Microsoft PowerPoint app provides compatibility, though macro execution is generally restricted on iOS and Android platforms.
