What is a .WIXMST file?
The .WIXMST file extension stands for a WiX Transform File. This type of file is made by a program called the WiX toolset, which is used to create installers for Windows software. Essentially, a .WIXMST file is used to show the changes between two different versions of software or two different XML files. It does this by keeping a record of the differences in a special table known as the MsiFileHash table. The content of a .WIXMST file is written in XML, which is a way of structuring data in a readable format.
To open or work with a .WIXMST file, you would typically use the WiX Toolset. This toolset includes a specific tool called Pyro. Pyro can take a .WIXMSP file, which is another type of file related to Windows installer development, and one or more .WIXMST files to create a .MSP file. An .MSP file is a Windows Installer Patch file, which is used to update software with new versions or fixes. So, in simple terms, the .WIXMST file helps in preparing updates or changes to software that can be distributed as patches.
