These things are called Command Line Arguments (for your reference).

You can retrieve them in a WinForms app by calling Environment.GetCommandLineArgs()

Command line arguments are space delimited, so if you entered /f:myfile.txt you would get "/f:myfile.txt" as a single argument in your application.

When you drag and drop, it simply passes the file path as an argument, which is exaclty what you want.
