Did you know, that for simple FTP tasks you don’t necessarily need an additional FTP-app on Mac OS X?
Just press Cmd+k in Finder or via menue ‘Go to’–>’Connect with server …’ and you will be promted with an URL-field. Just type e.g. ‘ftp://works13.com’, insert username and password in the next step, and your FTP Server is mounted in Finder, where you can use it like any other folder on your machine.
