File Formats: Microsoft Word Document (DOCX/DOC)

The DOCX and DOC file extensions are used for Microsoft Word documents, part of the Microsoft Office Suite of software.

DOCX/DOC files are used to store word processing data.

DOCX is part of Microsoft Office Open XML specification (also known as OOXML or OpenXML) and was introduced with Office 2007. DOCX is a zipped, XML-based file format. Microsoft Word 2007 and later uses DOCX as the default file format when creating a new document. Support for loading and saving legacy DOC files is also included.
