What is a .WIXMSP file?
The .WIXMSP file extension stands for a WiX XML Patch File. This type of file is made using a special program called the WiX toolset, which is used by people who create installers for Windows software. When developers are updating software, they often need to make small changes or "patches" instead of creating a whole new installer. The .WIXMSP file is part of how they do this.
Here's a bit more detail on how it works: When developers are building a patch, they start with files called .WIXOBJ. These files contain parts of the software that might need to be updated or changed. The WiX toolset takes these .WIXOBJ files and links them together in a special process. The result of this process is the .WIXMSP file, which is essentially a collection of these changes in XML format. XML is a way of organizing information that both humans and computers can understand.
To use the .WIXMSP file, developers don't open it like a word document or a picture. Instead, they use it with a specific part of the WiX toolset called Pyro. Pyro takes the .WIXMSP file and one or more .WIXMST files (which are template files) and combines them to produce a final .MSP file. This .MSP file is the actual patch that can be distributed to users to update their software.
So, if you come across a .WIXMSP file, it's a piece of a larger process used by developers to update Windows software. The main program you need to work with this file is the WiX Toolset, specifically the Pyro tool within it. Regular users typically won't need to open or directly interact with .WIXMSP files, as they are more for developers working on software updates.
