RARは現時点で唯一の機能です。
コマンドラインから、-osスイッチを使用します
-os Save NTFS streams. Windows version only.
This switch has meaning only for NTFS file system and allows
to save alternative data streams associated with a file.
It is especially important in Windows 2000, XP and newer,
which use streams to keep some file dependent information
like file descriptions. If you use RAR to backup your
NTFS disks, it is recommended to specify this switch.
WinRARのGUIでこの機能がどのように表示されるのかはわかりません。
