But I've tried 3 FTP clients to see which one was the best, and then decided to make a topic of which is your FTP client software (or what ever it's called, I also included online/web browsing FTPs that act as they were software).
I'm not an expert on this, in fact I just know how to connect and upload (that's what FTP is lol), not any other advanced stuff.
The 3 first options on the list are the ones I already used, and my favourite one has to be FireFTP as it's an add-on for Firefox which, of course, can be ran simply in a browser tab.
The rest I picked from Wikipedia. If you don't find your favourite there, just pick "Other" and tell me here in a reply. If your pick gets popular I include it on the poll.
