Technical details🔵 The `.docx` format, launched with Microsoft Office 2007, replaces the older `.doc` format in Microsoft Word. It's based on the Office Open XML standard, using XML to detail document structure and content, making it more transparent and easier to process. `.docx` files are zip archives containing XML files and resources, with folders like 'word', 'docProps', and 'rels' for text, properties, and relationships. Main text is in `document.xml`, with separate files like `styles.xml` for styling and directories for embedded media. This format enhances interoperability, reduces file sizes, and improves corruption recovery. It's supported by most modern word processors, with Microsoft offering compatibility packs for older Word versions. For security, macros are in a separate `.docm` file. `.docx` is a step forward in document format technology, emphasizing openness, interoperability, and efficient data management.
