If you need a good ftp client, you should give UltraFXP a try:
Notice that the makers of UltraFXP were legally threatened by the makers of FlashFXP, and hence the decision to make UltraFXP freeware. The funny thing is, FlashFXP argued that UltraFXP copied its interface. I don't know, but to me most FTP clients look more or less the same (they have two windows, with one window displaying your local browser, and the other the remote server). Oh well, you can read more about it here:
Edit: I've attached the chat log and the email, in case it gets erased by someone...sorry, but the whole thing just ****es me off! Just look how the lawyer first threatens this kid, and afterwards tries to seduce him to join his client's company ("I'm not suggesting you drop UFXP altogether... I suggest you work with FFXP on making it a better product and get paid that way...") YUCK!
