If you set unix_style option to false, the Pliant FTP server will use a different format for the 'LIST' command.
The advantage of this format is that it carries more informations.
The disadvantage is that it is not standard.
Anyway, Pliant clients will be able to force this format even if you don't force unix_style to false when starting the server, so using this option is not recommended.

An example:

pliant module /pliant/protocol/ftp/server.pli command 'ftp_server unix_style false name "FULLSERVER"'
