I thought that ssh cliant putty are needed to be use initialase file. I don't think so on now. I rethink that why putty developer don't add external initalize file ability. And find that this dicision is very courseable thing. Why we use ssh instaed of telnet. it because the security reason. If external initalise file is able to be used. handling external initalise file might be one of seculity hole, if the ssh cliant is clacked. I think the process to reinitialize property is not so hard. I should do so.
