What is the difference between .ac3 and .dotm?

Description: Audio file saved in the AC-3 (Dolby Digital) audio format; can include up to six channels of audio (DD 5.1 surround sound with subwoofer output); uses lossy compression and often used as the format for DVDs, cinema theaters, and game consoles.; A DOTM file is a Word Open XML Macro-Enabled Document Template used by Microsoft Word, part of the Microsoft Office suite. It is a template file that contains default layouts and settings for a document, including macros, which are small programs that automate repetitive tasks. Unlike standard Word templates (.dotx), which do not support macros, DOTM files enable users to include custom macros that can be executed within the document. This feature is particularly useful for creating standardized documents that require specific automated functions.
