:( With the previous implementation, streams could also be added/removed to directories, are rare feature found on the net, but truly supported using Win32

This is a nifty feature because for example you can now also get the real size used by a folder,
because of alternate data streams.

FindFirstStreamW does not work on directories, that why I didn't use that.

Uhm, in my tests these work fine on directories as well. Also adding streams to directories works fine still.

For example:

// E:\Test is a directory
foreach (var stream in File.EnumerateAlternateDataStreams(@"\\?\E:\Test", PathFormat.LongFullPath))
{
   Console.WriteLine("Name: {0}", stream.StreamName);
}

using (FileStream fs = File.Open(@"\\?\E:\Test:myStream", System.IO.FileMode.Create, System.IO.FileAccess.Write, System.IO.FileShare.None, ExtendedFileAttributes.BackupSemantics, PathFormat.LongFullPath))
{
   fs.WriteByte(24);
}

If you want the other stream information, eg. non-data streams you can get those by using BackupFileStream. So no functionality has in that sense been removed.
