What is PPTX file?

Files with the PTTX extension are files created with the Open XML format, and they contain data of a multimedia presentation, created usually with one of the elements of Microsoft suite – PowerPoint. In Open XML standard, the contained data is not stored in a singular binary file, but in a collection of separate files, compressed into a ZIP package. In the component files of a PTTX package, the stored data concerns:

  • slideshows
  • descriptions of slides in text form
  • formatting
  • drawings
  • images
  • animations and other multimedia data

Advantages of PTTX format

PTTX files are characterised by a high availability of the contained data. The available images are stored in separate files, and the slide shows, as a text files.

The most popular ones include: Microsoft PowerPoint, OpenOffice Impress, or LibreOffice Impress.
