Reformat Password

Somebody gave me a ftp account and some space to upload crap I forgot the password to it. Its been a long time since I've talked to him and he forgot his password so I can't ask him to change my password and I want to reformat. Is there a way to get the password or copy a file or registrey key so I don't lose the saved password?

Please somebody help me

Hi, go to tools, settings, interface, and enable show passwords.
