What is a PPS file?

The PPS (PowerPoint Show) format is a legacy binary file used by Microsoft PowerPoint 97-2003. Technically identical to the .PPT format in its Compound File Binary Format (CFBF) structure, the distinction lies in the file header flag that triggers the application to open directly into 'Slide Show' mode rather than 'Edit' mode. It encapsulates slides, audio, and transitions for immediate playback.

How to open a PPS file

PPS files are designed to launch automatically in presentation mode when double-clicked in Windows. To edit the file rather than view it, users must open Microsoft PowerPoint first and drag the file into the window. Third-party tools like LibreOffice Impress and Kingsoft Presentation also support this format, though some complex legacy transitions may render differently than in the original Microsoft engine.

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.
