Looking for an advanced FTP client software

Hi all,
I want to upload some files to my website. So I am looking for an advanced FTP client software solution designed for ease of use by both novices and professionals. It should be powerful and secure file transfer solution. It should also have total control, security, efficiency, and simplicity. If you people have any idea then please let me know.
Thanks in advance!

Hi, I use AnyClient when I need file transfer. It is a free platform independent file transfer application that supports all major file transfer protocols including FTP/S, SFTP and WebDAV/S. AnyClient is available both as a web based service requiring no software installation, and as a downloadable application that you can install locally. Hope this will help you.
All the best!

I use a program called CuteFTP by Globalscape.

"CuteFTP is the world's most popular choice for a reliable file transfer client. Whether you are publishing a Web page, downloading the latest digital images, music, or software, CuteFTP Home gets the job done every time. Use of industry standard protocols like FTP, FTPS, HTTP, HTTPS and SSH are part of what make CuteFTP Professional the ultimate in power, performance and security. Mac version also available."
It is relatively inexpensive and you have a choice of "home" or "professional" versions.
