The Synchronet file transfer section is used to facilitate transferring (sending or receiving) of files between the BBS and remote users. Historically, these file transfers took place using legacy “modem” file transfer protocols such as XMODEM, YMODEM, and ZMODEM (which are still supported today in the Synchronet terminal server and many, but not all, modern terminal programs). However files may also be transferred via Internet TCP/IP file transfer protocols, e.g. Gopher, FTP(S), SFTP, HTTP(S), BinkP(S) and E-Mail.
