Using the OS mechanism for copying files allows the OS to optimize the transfer using stuff such as [Offloaded Data Transfers (ODX)](https://msdn.microsoft.com/en-us/library/windows/desktop/hh848056%28v=vs.85%29.aspx). Also preserves a lot more information, including NTFS [File Streams](https://msdn.microsoft.com/en-us/library/windows/desktop/aa364404%28v=vs.85%29.aspx), which the manual implementation threw away. In addition, it is an atomic operation, unlike the manual implementation which has extra calls for copying over permissions. r? @alexcrichton |
