* Changes the name of the file this <code>SmbFile</code> represents to the name

     *
     * <i>Remember: <code>SmbFile</code>s are immutible and therefore
     * the path associated with this <code>SmbFile</code> object will not
     * change). To access the renamed file it is necessary to construct a

     *

 * resources are files and directories however an <code>SmbFile</code>
 * may also refer to servers and workgroups. If the resource is a file or
 * directory the methods of <code>SmbFile</code> follow the behavior of
 * the well known {@link java.io.File} class. One fundamental difference
 * is the usage of a URL scheme [1] to specify the target file or
 * directory. SmbFile URLs have the following syntax:
