How to send Flat file to FTP

Hi All,
can anybody tell me what services I need to invoke to send the flat file to FTP.

Please review the wM documentation.

Hi Reamon,
Can you please let me know the name of that guide.
It will be great help If you also tell me the name of services which needs to invoke.

Name of the built in services guide: Integration Server Built-In Services Reference.pdf”

All the FTP services browse in the Client folder in the pdf – pub.client.ftp folder (WmPublic IS package) and other general services also.
