FTP using cURL

Hi

I am trying to fetch a file from a remote location and download it into a local directory ...i was previously doing it quite simply using ftp but now i need to do the same using the cURL tool ...Here i am not getting an option to specify a directory name i am trying the following but doesnt work ...any help/suggestions please

curl -v -u $USER:$PASSWD --ftp-ssl --insecure ftp://164.233.45.123/D9694396.D364817713.DWA0411.Z --ftp-create-dirs mydir

Here mydir is the local directory where i want to download the file

Thanks
Jamshed
