Transferring files via FTP

I am wanting to transfer files from an SDC Ultra to a normal FTP server. I have setup a share and username/password for it. It can ping with no issues but always failed on upload. Is it trying to write to the root directly of the FTP server i.e. ftp://192.168.123.123/ and can it be possible to point it to a folder instead i.e. ftp://192.16.123.123/folder/
