.DOTX File Extension

Template file created by Microsoft Word, a word processing program; contains default layouts and settings for a document, including styles, AutoText, toolbars, and macros; used as a baseline to create multiple .DOCX documents with the same formatting.

The Normal template is the default template that is opened when users open Word. It is stored in the file Normal.dotx and can be modified to create custom default template settings.

DOTX files use the newer Open XML-based Word document format, which was introduced in Microsoft Office 2007. They can opened in Microsoft Word 2007 or previous versions of Word with Open XML component support.
