        <p>If the target object's and the <c>DestinationFile's</c> associated
          <c>FileTransferSession's</c> support the same protocol(s) this operation
          will copy the file represented by the <c>SourceFile</c> from the target 
          object's file system to a file in the destination 
          <c>FileTransferSession's</c> file system. The file is represented by the
          <c>DestinationFile</c> object and may not exist.
          This operation must be invoked on the <c>FileTransferSession</c>

        <p>This operation behaves almost like the <c>transfer/3</c> operation. The
          difference is that the <c>DestinationFile</c> must exist since the

        <p>Currently, it is not possible to use this operation when the target
