>I wonder if someone could recommend an FTP client (hopefully free). I am using FileZilla and I am having a problem uploading files to my FTP. I don't know if the problem is with my ISP or FileZilla but I thought it would be a good idea to have another FTP client; to double check.

FileZilla is assumed to be pretty robust. I would probably think the problem is with the server.

I also use Ipswitch WS_FTP Professional.
