What is MUI file?

The Multilingual User Interface, laying behind the MUI file format, is a technology developed by Microsoft for Windows system, MS Office and other software, which enables installation of multiple interface languages. Content of MUI files is data for a program or a .DLL file, which are necessary to change interface language within a given program.

Interesting facts about MUI files

  1. It is worth mentioning, that MUI format has emerged only in the Windows 2000 system, and is obviously present in all the newer versions.
  2. According the presumption, MUI files take names after .EXE or .DLL files they refer to, for example: notepad.exe.mui. However, it just a guideline, which is not always reflected in a system.
  3. Every MUI file is assigned with a location, in which data concerning a given language is contained, therefore such files are usually encountered in subfolders with names including specific languages. For instance, within WINDOWS 7 operating system, there are 35 versions of the tipresx.dll.mui file, located in the following directories:

    \Program Files\Common Files\microsoft shared\ink\ [language symbol] \tipresx.dll.mui
