I am by no means an expert in the ftp protocol or ftp software. I used to use a cracked version of CuteFTP, but it is proprietary. FileZilla's name derives from the open source Mozilla Project, but I do not think it is directly associated. If you are not using Mozilla Firefox as your web browser, you probably should be - especially if you are still using M$ IE. Filezilla is free and open source. With a clean interface, it accomplishes everything the average user would want out of an ftp client. I have not used the server, but I believe it to be similarly useful.
