You mean the default setting/switch? If so, it depends on the FTP server, for example with vsftp is force_dot_files which by default is off. So the client has to do list -la to show them. proftpd uses ListOptions -a to change the default. The FTP server you use may have a configuration setting for it, but its name may not include the word hidden.
