Kernel-Mode File Copying

Is there any function which can copy files using kernel-mode functions? I expected to find a function called ZwCopyFile, but it doesn't exist. How do you copy files?

Have you tried using ZwCreateFile, ZwReadFile and ZwWriteFile. Also make sure its not too early in the game if yours is a driver loading during boot process.

Thanks!

So apparently there is not direct copy routine... you need to read, write, read, write... right?
