How to enable ftp on alfresco 5.1?

Hi,

I enabled ftp by adding the below properties in alfresco-global.properties.

### FTP Server Configuration ###
ftp.enabled=true
ftp.port=2121

Are there any other property files need to be modified to enable ftp server on alfresco?

I get a user-id password prompt but after successful login, nothing happens. ftp url - ftp://alfresco-test:2121/alfresco

In documentation, i see it is required to update file-servers-custom.xml but I do not see that file existing in alfreco, is this file available in community version?

Server: Alfresco Community 5.1

Please advise.
