Copy a file without using the windows file cache

Question

Anybody know of a way to copy a file from path A to path B and suppressing the Windows file system cache?
Typical use is copying a large file from a USB drive, or server

Answer 1

Even more important, there are FILE_FLAG_WRITE_THROUGH and FILE_FLAG_NO_BUFFERING.

MSDN has a nice article on them both: http://support.microsoft.com/kb/99794
