This may have something to do with FTP having two modes, passive and
active (i think the other is active). Anyway in one of these two mode
FTP is a dynamic protocol. It opens one port usually 21 to send commands
and another port to send data. It sounds like ZA is allowing the
commands port (ie. you are connecting) but not allowing the data port
(ie. you cannot see folders, copy files etc).
You have two options if this is the case:

1. Try to find on google how to config ZA for FTP in active mode.
2. Get your FTP app to connect using Passive mode.

Cheers P.

PS. the commands prompt FTP must use passive mode.
