What is a .PSM1 file?
The file extension .PSM1 refers to a Windows PowerShell Script Module File. This type of file is a script used by Windows PowerShell, which is a more advanced version of the Windows Command Prompt. Windows PowerShell allows for more complex operations and scripting capabilities.
A .PSM1 file contains functions and variables that can be grouped together as a module. These modules can then be included and used in other PowerShell scripts, typically with the .PS1 extension. This is useful because it allows you to reuse code across multiple scripts without having to rewrite or copy the same functions and variables each time.
For example, if you have common tasks or routines you use frequently, you can save these in a .PSM1 file and then simply include this module in your other PowerShell scripts. This makes your scripts neater and easier to manage.
To open a .PSM1 file, you can use Microsoft Windows PowerShell, which is included with the Windows operating system. This program provides the environment needed to execute the scripts and modules written in PowerShell.
Additionally, it's worth noting that .PSM1 files are often associated with .PSD1 files, which are PowerShell Data Files used to store module manifest data. These manifests provide metadata about the module, such as the author, version, and capabilities of the module, helping to manage and share PowerShell modules more effectively.
