title: Having XCopy copy a file and not overwrite the previous one if it exists (without prompting)
body: <p>I'm sending a commands to a remote computer in order to have it copy a file.
  I want the file to be copied, but not to overwrite the previous file with the same name (if it exists).
  I also need the command to run without any prompts (xcopy likes to prompt whether the target name I've specified is file or directory, and it will also prompt about overwriting a file).</p>
