I'd like to present you Steed, which started its public beta almost 2 monthes ago. I'm one of the developers of the application, and we've been working hard for months on this project.
It is an FTP, SFTP, Azure and S3 client, it allows you to browse and transfers file from each of these "protocols". We though Windows needed an file transfer client, that was visually appealing, easy to use, and up to date.
We know there is a lot of other FTP client on the market, but we though this one would bring something new to the Windows application ecosystem.
You can find it at : http://www.frenchfrysoftware.com/steed, it requires Windows XP SP3, Vista, 7, and it might also work on Windows 8, even if it is not officially supported for now.
Even if it is the third beta, keep in mind that it is still a beta!
In order to improve it, you can provide us feedback on our support page (http://www.frenchfrysoftware.com/steed/support.html), or you can contact us via twitter (@frenchfryapps)
I hop you'll enjoy it!
