Dreamweaver's built in FTP client gives me nightmares. I used to use CuteFTP, now I'm 100% converted to FileZilla. It's free, it's tight, and it rocks.
CuteFTP is the best FTP program out there. But my license expired and now im using smartFTP. - Prilep
I use FileZilla for my major updates but my day to day, I use a little FTP program called Child's Play. It updates only what have changed in a certain folder. It makes updating fast.
