set up Filezilla Server to transfer files to a mapped network drive

Please read carefully before sending bids: I have installed and set up a Filezilla Server on my laptop, which gets data from a sensor directly connected to it. However, I need to send these data to another server (which uses SFTP). This other server is mapped as a network drive. What I would like to do, is setting up Filezilla server so that it seamlessly transfer these file to the SFTP server.
