All about OTP files

OTP, OpenDocument Presentation Template, is a template format for presentations in the OpenDocument standard (ODF). The format was released in 2005. When opening an OTP file (unlike ODP), the application opens a new, untitled presentation based on the template. The original file remains unchanged.

OTP templates can include master slides, backgrounds, colour schemes, fonts, effects and much more, and are often used as templates in CI/CD across departments or companies.

OTP is natively supported by LibreOffice Impress and Collabora Office. Microsoft PowerPoint has been able to open OTP files since version 2007 SP2, but complex formatting may differ in the display.
