    The + symbol in [Environment+SpecialFolder] is used to indicate that SpecialFolder is an enumeration
    within the Environment class.
    In .NET, the + symbol is used to denote a nested class or enumeration within another class. So, in this
    case, SpecialFolder is a nested enumeration within the Environment class.
    To use the SpecialFolder enumeration in PowerShell, you need to specify the fully qualified name of
    the enumeration, which includes both the name of the parent class and the name of the nested enumeration,
    separated by the + symbol.
