Win32 access over "WinFS" also boosts the performance of new Windows applications written for "Longhorn" when they access large file streams. "WinFS" file items consists of attributes for the meta data in the store, and streams for the content in the underlying NTFS volume; therefore, Win32 access over "WinFS" allows a direct access to the NTFS file streams so that applications can read or write a file more efficiently than with "WinFS" API.
