FTP does the trick. I don't think wrfile would have worked for me as I needed to create directories.
To enable it use the following command
options ftpd.enable on
Please note that it uses the password hash found in the /vol/vol0/etc/passwd, not what you use for your normal root login. To set the password need to create a hash with the following command.
cifs password MyPassword
You can then put this hash in the /etc/passwd (I was able to use CIFS for this).
Thanks for the help
