MSM File – What is .msm file and how to open it?
MSM File Extension
Windows Installer Merge Module – file format by Microsoft
MSM file extension is associated with Windows Installer Merge Module, a file format developed by Microsoft to bundle files and registry settings needed to install or update software components in Windows systems. It allows for modular software installation and patching.
MSM File Overview
A MSM file is a Windows Installer Merge Module, a component used to extend the functionality of Windows Installer packages (MSI). It contains pre-compiled data and resources that can be integrated into an MSI package to enhance its capabilities. MSM files typically include additional features, components, or updates that cannot be easily included in the original MSI package. By merging MSM files into an MSI package, administrators and developers can customize and extend the functionality of the MSI package without having to modify the original source files.
Benefits of Using MSM Files
MSM files offer several advantages over directly modifying the original MSI package. Firstly, they allow for modular customization, enabling administrators to add or remove components without affecting the base MSI package. This simplifies the process of updating and maintaining MSI packages, as only the affected MSM files need to be modified. Additionally, MSM files allow for code reuse and sharing of common components among multiple MSI packages. This helps to reduce development time and effort, as well as ensure consistency and compatibility across different MSI packages.
Opening MSM Files in Windows
To open MSM files in Windows, you can use the Microsoft Windows Installer (MSI). MSI is a software installation and configuration tool that is included in Windows operating systems. To open an MSM file using MSI, follow these steps:
- Open the Windows Command Prompt (cmd) as an administrator.
- Navigate to the directory where the MSM file is located.
- Type the following command:
msiexec /a [MSM file path] - Press Enter.
The MSM file will be merged into the MSI package. You can then use the MSI package to install the software on your computer.
Third-Party Tools for Opening MSM Files
If you do not have MSI installed on your computer, you can use third-party tools to open MSM files. Some of the most popular tools include:
These tools allow you to view and edit the contents of MSM files. You can also use these tools to merge MSM files into MSI packages.
Windows Installer Merge Module (.MSM)
Windows Installer Merge Module (.MSM) is a file format used for combining multiple Windows Installer packages (.MSI) into a single, cohesive unit. Developed by Microsoft, MSM files facilitate the modularization and reuse of common components or functionality across different MSI packages. By merging multiple MSIs into an MSM file, administrators and developers can streamline the installation and maintenance of software applications.
The process of creating an MSM file involves using the Merge Module Authoring Tool (Msimt.exe), provided by Microsoft as part of the Windows Installer SDK. This tool allows authors to specify the contents of the MSM file, including the component groups, features, and dependencies from the source MSI packages. Once an MSM file is created, it can be included as a dependency in other MSI packages or distributed independently.
