directory on disk redirect cannot be deleted with win2008 , if file exists on the directory.
I already patched "ID: 2894210".
I think disk_close() in disk.c is fail.
when delete directory with win2003 , win2003 is request to recurrently delete the all file in directory before delete directory.
but with win2008 , request to delete just only directory.
directory cutout also fail.
