What is an MSM file?
Database of a "merge module" that contains installation settings and properties for a specific software installer; includes files, resources, registry entries, and setup information; often contained within an .MSI file.
MSM files are also called "merge package files." Since they are usually part of an installer package, MSM files should not be opened manually.
