FlashFXP is amazing. They have a free 2 month trial. I have used it for years on trial, but recently paid $15 or so for a license, as they accept paypal
I use FireFTP. It is a firefox plugin and lets you FTP right in the browser. Used to use smart ftp but now there is no need. It is quick, light, and you don't have to open another app http://fireftp.mozdev.org/
Filezilla Has been great to me.. I have used a lot of the the others and always have problems... Fillezilla all the way
thanx for the info... my friend wanted just that for windows..and cheap..only 15$ but i'll always be promoting linux..
