Opening MST files

Did your computer fail to open a MST file? We explain what MST files are and recommend software that we know can open or convert your MST files.

What is a MST file?

Files that contain the .mst file extension are used by the Microsoft Windows operating system to customize the installation settings for Microsoft Windows Installer applications. The MST file can change the properties of a Windows Installer, allowing different user groups custom installation options when installing different computer applications.

MST files are commonly used for software testing and development purposes. These files contain different software configurations and custom software parameters that are built during the software development process. An MST file is usually only one part of a complete installer package, with the actual installer package containing the .msi file suffix.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
