Pay up. :-) The Internet only works (most of the time) because we DO have faith! Though, sometimes, it is just sheer luck. Except for file lists (NLST), an FTP client must not interpret the textual information that the FTP server generates. While the client cannot infer the reason for the 550 it knows that the transfer did not take place. I think VMFTP only interprets textual responses generated localy by the FTP *client* such as a syntax error on a PUT. That's why the VMFTP code is (by casual code inspection) looking for > C'000' in the first 3 characters of output. Sir Alan, Lord of the Protcols
