I think you are mixing things up. FHFS is an FTP and HTTP server, all in one. So it gives you 2 different protocols, and 2 different ways to upload files: through FTP and HTTP. To upload via FTP you need a FTP Client software, and via HTTP you can use any web browser.
I don't get what you mean "like an FTP server" (FHFS is a FTP server!)
