Ftp is nothing more then a sort of client to client browser. For the data donor it has a mayor advantage that he does not have to rent a server to put his data on but can use a computer at home for this server purpose. Furthermore he can grant acces to who he wants. This to help manage costs in File Transfer. The client , the one who wants the data will need a program like filezilla a link to the File Transfer server and a password. Nowadays when big data can be cheaply stored and shared and controlled by data owner,like google drive,there is much less benifits to use a ftp server.
