What is a .docx file?

The DOCX file extension represents a Microsoft Word Open XML Document. Introduced with Microsoft Office 2007, it's the default file format for saving documents created in Microsoft Word. DOCX files store formatted text, images, tables, charts, and other document elements. The format is based on XML and ZIP compression, making it more compact and less prone to corruption compared to older DOC formats. This open standard allows for better interoperability with other applications and operating systems. DOCX files support a wide range of features, including advanced formatting options, macros (though these can pose security risks if not handled carefully), and collaboration tools like track changes and comments. The format's structure allows for easier recovery of data in case of file corruption, as the document is essentially a collection of XML files within a compressed archive. The use of XML also makes it easier for developers to programmatically manipulate DOCX files. It is widely used for creating and sharing documents across various platforms and devices.
