Require help in moving file from FTP to LAN directory

Hi all,

I have a requirement to move the file from the Source FTP server and place the file in the Target LAN directory.
I have configured a File polling port to copy the file from source to done directory(They need to have a back up with wM).
The file polling is working as expected.However I am not sure how to move the file to the Target LAN directory.
we have implemented Trading partners to log the transaction for each partner.
Requesting your help on this.
