I don't use dreamhosts webftp client. ftp in general is not secure and should not be used, as such all my "users" have "disallow ftp" checked. As a result of that, it's not easy for me to just go look in their interface and check for you.
It would be best if you downloaded an ftp client and set it to use SFTP as the protocol. Popular with beginners is filezilla, another good one is FireFTP which is actually a browser plugin. WinSCP is often popular for the experienced but likely harder for beginners.
