there are a good handful of free FTP clients.
WSFTP is the mainstay freeware one - the one I seen professional webmasters using for years.
I use mainly Cute - though it has its shortcomings. Like it won't automatically refresh local folders when new content is added. That's payware though.
A great resource for free utility software is
www.nonags.comMuch easier to browse than download.com (et all) & you can select 'freeware only' & most of the well known free utility software is there.
Here's the FTP page - for instance
