DOCX
Microsoft Word Open XML Document
DOCX is Microsoft Word's default file format since Word 2007. It is built on the Office Open XML standard (ISO/IEC 29500) and stores documents as a ZIP archive containing XML files, embedded media, and metadata. Compared with the older binary .doc format, DOCX is smaller, more recoverable when corrupted, and openable by a wide range of non-Microsoft software.
