The .xml file extension is used for Extensible Markup Language files. XML files contain structured data developers use to store information. If an XML file contains macros, the file extension changes to .xmlm. XML and HTML work together in web applications. XML describes content related to stored data. Programs that open XML files work on all platforms, but may not properly support the files. XML files open in text editors or integrated development environments. The XML file extension indicates a text file. XML is a markup language used to structure data.
