Microsoft Word Document (.docx)
The DOCX file extension stands for "Document Open XML", a Microsoft Word Document format introduced in Office 2007. It uses XML and ZIP compression technology to create smaller, more efficient files compared to the older DOC format. DOCX files are widely used for creating, editing, and sharing professional documents, ensuring compatibility across various platforms and devices. This format supports advanced features such as macros, formatting options, and multimedia elements, making it essential for modern document processing in the IT and business sectors. Its history reflects Microsoft's ongoing efforts to enhance document interoperability and efficiency.
