Files with the PSD1 extension are associated with the Windows PowerShell command interpreter. PSD1 is an optional file accompanying the more complex PSM1 modules, although it is recommended to use PSD1 files whenever possible. A PSD1 file is a text file that describes the contents of the module and how it is processed. It allows for the optimal organization of the module code. It contains data about its version and an array of keys and values. To link the manifest file with the module, put them in the same directory.

PowerShell allows you to automate Windows tasks. It is based on a text interface related to a scripting language based on the .NET Framework.
