The answer .docx is commonly associated with newer versions of Microsoft Word and represents a file format that uses XML (Extensible Markup Language). This format offers advantages over its predecessor, .doc, such as reduced file size and improved recovery options. It’s widely used for creating and editing word processing documents, making it the standard for documents that include complex formatting, images, and embedded objects.

While .pdf is used for Portable Document Format files, which are typically read-only and used for sharing documents without allowing edits, and .doc is older, proprietary to Microsoft Word, .docx provides a modern, standardized approach to text documents. The .txt extension is for plain text files and lacks the formatting capabilities of word processing documents. Therefore, .docx effectively denotes a common file extension specifically tailored for use in word processing, catering to a range of document creation needs.
