dotm A .dotm extension file is a Macro-Enabled Template file that is created using the Microsoft Word Processor. The .docm file format is very useful in corporate offices and large-scale business where there is a need for mass communication to be sent out in a standard format. In such cases, a template can be created with all the standard specifications and formatting. Macros can be written to execute a set of standard commands, and the template can be saved and used, this saves time by eliminating the need to type or do the same tasks over and over again.
odt The Open Document Text filename extension format is an alternative open source document and text processing file format allowing users to create text documents that can be opened and edited by an extensive list of document processing applications. Both proprietary applications (such as in Microsoft Office word) and open source document processing applications (such as OpenOffice) support the .odt filename extension allowing for interoperability between software systems. The format is useful to those creating documents meant to target a wide audience and not necessarily an audience with a specific document processing suite. The extension was first released in 2005.
