I’ve been on the lookout for a good FTP client for Windows for a long time. I favor a simple interface that lets me easily move files between my computer and FTP site. I used LeechFTP for some time, then moved to Smart FTP. I found both reliable, but a little hard to get around in. I’m now a delighted user of the FireFTP extension for Firefox (for versions 1.5 - 2.0). It opens as a tab within Firefox and sports a simple, intuitive interface for moving files around. It also has all the features I could want from an FTP client.
