I've been using this program for about 6 months now, and it ROCKS.
It supports SSL (ie. secure ftp), FXP-like functions... and best of all, its 100% free.
No more dicking with CuteFTP Pro, or WSFTP Pro.
Give it a try... you'll love it.
They also have a ftp server, going to be checking that out this week. Get it from your favorite Sourforge mirror or :

Full information and such can be found at :

With the advent of this, I will be turning off regular ftp on my FreeBSD machine (image hosting, etc) and you will need to use this to connect. ETA - 1 week till regular FTP is disabled!
