org.apache.commons.net.ftp.FTPClient.changeWorkingDirectory()
Change the current working directory of the FTP session.
@param pathname The new current working directory. @return True if successfully completed, false if not. @exception FTPConnectionClosedException If the FTP server prematurely closes the connection as a result of the client being idle or some other reason causing the server to send FTP reply code 421. This exception may be caught either as an IOException or independently as itself. @exception IOException If an I/O error occurs while either sending acommand to the server or receiving a reply from the server.
