title: Is there a Win32 API to copy a fragment of a file on another file?
body: <p>I would like to programmatically copy a section of a file on another file. Is there any Win32 API I could use without moving bytes thru my program? Or should I just read from the source file and write on the target?</p>
  
  <p>I know how to do this by reading and writing chunks of bytes, I just wanted to avoid doing it myself if the OS already offers that.</p>
