Help finding filezilla server

I want to get Filezilla to send files to my web host from a drive that's networked to the computer where Filezilla is installed. I've read posts here that suggest changing settings in Administrative Tools / services. When I look
at the list of services I don't see any for Filezilla, FLZ or FTP or anything similar. Yet I am able to connect to my web host and transfer files from the system where Filezilla is installed so I know that Filezilla is a working service.
I looked at the services list when Filezilla was open and when it was closed, but this made no difference.

Can someone tell me where it's located and under what name or abbreviation?

Thanks.
