What is DOCX?
DOCX is the default file format for Microsoft Word documents, introduced with Microsoft Office 2007. It's based on the Office Open XML (OOXML) standard and serves as the modern successor to the older DOC format. DOCX files are actually compressed ZIP archives containing XML files and media resources, making them smaller, more secure, and easier to recover than their predecessors.
File Format: DOCX uses the .docx extension and is based on the Office Open XML standard. Files are ZIP archives containing XML documents, media files, and formatting information stored separately.
Structure: Unlike the binary DOC format, DOCX stores content as XML within a compressed ZIP archive. This modular structure includes separate files for document.xml, styles, settings, and embedded media.
Compatibility: Native support in Word 2007 and later, including Word for Mac, Word mobile apps, and Office 365. Older versions require the Microsoft Office Compatibility Pack.
File Size: Typically 50-75% smaller than equivalent DOC files due to ZIP compression, making them ideal for email attachments and storage.
Security: More secure than DOC with better macro handling and structure for detecting malicious content. Supports password protection and information rights management (IRM).
