Filezilla
A few years ago I used WSFTP when I needed to upload to a website. It’s been a long while since I maintained a website, so to help manage my new game development blog I looked around to see what else is out there these days. Lucky for me, I found FileZilla. Not only is it free and open source, it is a pleasure to use. If you are in the market for an ftp client, give FileZilla a spin and see how it fits.
