What is an OTP file

OTP files mostly belong to LibreOffice Impress. OTP files serve two main purposes. They are primarily used as OpenDocument Presentation Template files that work with presentation programs such as LibreOffice Impress or Apache OpenOffice Impress. These files are actually ZIP archives that hold XML data defining slide layouts, themes, and formatting rules.
Usage Cases:
  • Presentation Template: The file provides a preset design to build new slide presentations. It contains preset styles, backgrounds, and formatting details. For more information, visit the LibreOffice website.
  • One-Time Password: In some cases, an OTP file may store a temporary authentication code used once for security processes. This format is part of systems like OpenOTP.
    • FilExt.com tip: To view a presentation template OTP file, open it with a compatible application like LibreOffice Impress. If the file is used for one-time password data, it should be handled by that specific authentication software.

    How do you open OTP files?

    You need a suitable software like LibreOffice Impress to open an OTP file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your OTP file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a OTP file directly in the browser:. Just drag the file onto this browser window and drop it.
