Anyway to do SSL Data for directory listings only?

Hi, I'm connecting to glftpd 1.32 + TLS.

It seems I can connect fine using any of the builtin SSL modes (SSL, TLS, etc).

Now, GLFTPD supports SSL data on directory only, so that actual file transfers are done in clear-text. Setting it up as such makes file transferring a lot faster.

But, for the life of me, I can't figure out if or how SmartFTP supports SSL data on directory listings only.

Can anyone shed some light on this? An option to specify this would be really helpful
