Environment.SpecialFolder is a value-type that i always seem to forget about. Let’s try to do something about that by posting about it here 
foreach (var name in Enum.GetNames(typeof(Environment.SpecialFolder)))
{
var specialFolder = (Environment.SpecialFolder)Enum.Parse(typeof(Environment.SpecialFolder), name);
Console.WriteLine("{0,25} => {1}", name, Environment.GetFolderPath(specialFolder));
}
