FlashFXP or WinSCP on my PC, and Fetch on my iBook.

I prefer to use windows built in ftp capabalities, I don't see the lure in using FTP managers when you can use a windows folder much like any folder on your computer.

^ I prefer Filezilla because Its not like the standard folder system. I can drag a file from one side of a window to the other side of the same window and upload/download without having to go back and forth between windows like you do with Explorer.

I use CuteFTP, very happy with it.
