Best practice for large volumes of FTP data

We receive large volumes of EDI data from internal and external partners via FTP. Is there a best practice for how to best approach this type of scenario? Is it better to use the integration server’s FTP service, or use external scripts and FTP server?

I am new to Webmethods and just checking out all the documentation. If someone could just point me in the right direction, I’d appreciate it.

Thanks.
