Have you encountered a problem with a POTM file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a POTM file here. In the further part of this page we have added a list of programs that should open your POTM file. It is enough you choose a proper application for your operating system, download and install it.


Files with the POTM extension contain an Office Open XML macro-enabled Document Template, which is a template for Microsoft PowerPoint presentations. These files contain different formatting information, such as fonts and sizes, images and colors, as well as texts and macros. They can be used to create multiple documents with the extension pptm, all using the same style.

Microsoft supplies with PowerPoint some templates, but many templates are also available for free or Kuflich to purchase. Because POTM files contain macros, a scan for malware is indicated by an antivirus program.

The POTM files will be used by the Microsoft Powerpoint version 2007 (Mac 2008). The older versions 97 to 2003 use the extension pot for their template files.

Office Open XML is an XML-based file format that is unreadable with earlier versions of PowerPoint. For the Office versions 2000, 2003 and XP, this functionality can be used with the help of the Microsoft Office Compatibility Pack, whereby the result of an imported POTM file does not always have to correspond to 100% of the original.

Office Open XML is an open Bro Bro applications standard developed by Microsoft to provide file sharing between different Office suites.

A POTM file consists of several XML files, which are automatically compressed into an archive when saved using the ZIP algorithm. This saves space compared to the old format. Other benefits include better data integrity and easier data recovery in case of data loss.

How to open a POTM file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the POTM file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a POTM file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support POTM files. At this point we are looking for disk space where the application was installed in and we can link it with a POTM file. Since then, our operating system will use the selected program to support all POTM files.

Other issues

Despite the described problem with POTM there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the POTM file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the POTM file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
