/// <tt>dest</tt> parameter. This file and the destination file do not
/// need to be on the same host. This operation does not copy extended
/// file attibutes such as ACLs but it does copy regular attributes as
/// well as create and last write times. This method is almost twice as
/// efficient as manually copying as it employs an additional write
/// thread to read and write data concurrently.
