I've used FileZilla for years without any problems. It really is personal preference though.

I have used FlashFXP for years and would never use anything else. I think it performs great, but as always it is personal preference.

i used fireftp within firefox and was surprised on how easy and simple it is -- and how it just works -
although my fav is WS-FTP

I know i said earlier that i use SmartFTP but since i posted that, i have changed software to WinSCP. Its much better and its never times out which is good. I can also access the entire server if needs be

I have tried a few different FTP clients and have decided that FileZilla is my favorite FTP.

When I use an FTP at all, it tends to be Win_FTP...or I believe that's what it was called?

Most of the time these days, I just upload everything manually through my hosts control panel.

For me, I just find things to be quicker and easier when I do it that way.
