Files with the extension POTX contain an Office Open XML Document Template, ie a template for Microsoft PowerPoint presentations. These files contain various formatting information, such as fonts and sizes, images and colors, and texts can also be included. They can be used to create multiple documents with the extension pptx, all using the same style.
Microsoft supplies with PowerPoint some templates, but many templates are also available for free or Kuflich to purchase. The templates can not contain macros. Files with macros are indicated by the extension potm.
The POTX files will be used from version 2007 of Microsoft Powerpoint. The older versions 97 to 2003 use the extension pot for their template files.

This may happen because no default application was associated with this type of files. To associate POTX files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the PowerPoint applications is not on the list, select "Browse" option in order to manually locate the directory where PowerPoint has been installed.
Sometimes problems with opening POTX files may not lie with the application itself, but can arise due to other causes, such as:
