What Is an XAML File? A file with the XAML file extension (pronounced as zammel) is an Extensible Application Markup Language file, created using Microsoft's markup language that goes by the same name. XAML is an XML-based language, so .XAML files are basically just text files. Similar to how HTML files are used to represent web pages, XAML files describe user interface elements in software applications for Windows Phone apps, Windows Store apps, and more.
