What is DOTM file format?

The DOTM file format is a file format developed by Microsoft to be used in conjunction with the Office Open XML file formats. The DOTM file format is not compatible with other Office formats such as DOCX and PPTX, so it needs to be converted before it can be used. The DOTM file format contains documents, templates, and macros that can be used to automate tasks within Microsoft Office applications. It is used to store information that is shared between Office applications. The DOTM file format was introduced in the Office 2007 and the later releases of the Office suite. With DOTM files, users can create a template, add macros to it, and save it for use in any Office application. This allows for quick and easy sharing of data across multiple applications. Furthermore, it also ensures that all Office applications can access the same data, making it easier to collaborate on projects. The DOTM file format is useful for quickly creating templates and macros that can be used across multiple Office applications. It also allows users to store data securely, making sure that only authorized personnel can access it. Finally, it helps to ensure that users can quickly and easily share data across different Office applications.
