proftpd default setting ListOptions

[kilburn]

Have you tried checking "Show hidden files" option in your preferred FTP client? The default server's configuration doesn't display them on normal list, but the client is allowed to explicitly request it to also show hidden files (-a modifier to the LIST command issued by the client).

IMHO it's ok the way and there's no need to modify anything (as hidden files should be hidden by default, as it's name implies!)
