Files that contain the .potx file extension are used by the PowerPoint presentation software application. PowerPoint is a program that allows users to create dynamic presentations and slide shows.
The POTX files that are used by the PowerPoint software application contain PowerPoint templates. These templates allow a user to save default file settings in the PowerPoint application, allowing the user to re-apply the same layout settings across multiple PowerPoint presentation files without having to create each file from scratch.
Companies often use the POTX file format to create standard master slides which contain the company's header, footer and logo.
The POTX file format is based on the Open XML format, which was only included in versions 2007 and later of the PowerPoint product.
