What is a POTX file?

POTX files mostly belong to PowerPoint by Microsoft. POTX is an XML-based design template file used by the presentation software Microsoft PowerPoint.

Format: The new format used by POTX (and other Office "X" files) is a zipped, XML-based format initially standardized by Ecma, and later by ISO and IEC. Its specification is published as an open standard.

Benefits: POTX is a part of the newer XML-based standard that Microsoft implemented to replace the old binary-based format. When compared, the benefits of the newer format include:

• Smaller file sizes, up to 75% smaller than comparable binary documents;
• Security, through being able to identify and exclude executable macros and personal data;
• Less chance to be corrupted than binary formats;
• Easier interoperability for exchanging data among Microsoft and other business applications, all while maintaining backward compatibility.

Compatibility: Office Open XML format files can be opened by any Office programs that support it, not just by those created by Microsoft.
