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.
