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

I understand this question was 11 years ago, nowadays there is robocopy which is kind of replacement for xcopy.

you need to check /J option /J :: copy using unbuffered I/O (recommended for large files)
