What are MUI files and how to open them
Are you having problems opening a MUI file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your MUI files.
What is a MUI file?
MUI stands for Multilingual User Interface. Files that contain the .mui file extension are resource files that are used by Windows operating systems, versions 2000 and later. The MUI files contain resources that allow you to change your Windows interface to display different languages. For example, if you prefer your user interface to be displayed to you in German or in Spanish instead of English, your MUI files would allow this to happen.
While files with the .mui extension are most commonly associated with the Windows Multilingual User Interface, they can also be created by an Open GL toolkit used to write OpenGL programs.
