Questions & Answers
DOCX documents: Frequently Asked Questions
What are DOCX files?
DOCX is the Office Open XML format for word-processing documents, standardized as ECMA-376 and ISO/IEC 29500 and used by default in Word since Office 2007. A DOCX file is a ZIP package, so it can be renamed to .zip and opened with an archive program. The main text is in the document part, and other XML parts hold the styles, the numbering of lists, the fonts, the settings, the headers and footers, footnotes, and comments, while relationship files and a list of content types link everything together. Pictures and other media are stored as separate files in a media folder, and the XML text is compressed in the archive, so a DOCX file is usually much smaller than the same document in the older DOC format. Because every part is stored separately, a damaged picture does not destroy the whole file. The format cannot hold macros: a document with macros uses the DOCM extension. The structure is open and well documented, which makes it easy for other programs and services to read and create such files. Supported by Microsoft Word.
