What is the extension of a word file?

The extension for a Microsoft Word document file is typically ".docx." This extension is used for Word files created in versions of Microsoft Word from 2007 onwards. Word files with the ".docx" extension are based on the Office Open XML (OOXML) file format and are the standard file format for Microsoft Word documents. It's important to note that earlier versions of Microsoft Word, such as Word 2003 and earlier, used the ".doc" extension for their document files. However, with the introduction of Word 2007, Microsoft transitioned to the ".docx" format as the default, which offers improved compatibility and features. In addition to ".docx," you may also encounter other file extensions associated with Word-related documents, such as: • ".docm": This extension is used for Word documents that contain macros (small programs or scripts) written in Microsoft Word's VBA (Visual Basic for Applications) programming language. • ".dotx" and ".dotm": These extensions are used for Word document templates, with ".dotx" being for templates without macros and ".dotm" for templates with macros. • ".rtf": Rich Text Format is a file format that is not exclusive to Microsoft Word but can be opened and edited in Word. It is a more basic text format that retains formatting and is often used for document interchange between different word processing applications. When working with Word documents, the specific extension you encounter will depend on the version of Microsoft Word used and whether the document contains macros or is a template.
