The invention discloses a file sending method, a receiving method, a system and a device, belonging to the field of communication technology. The method includes: the binary file transfer protocol data transcoding into string data; the string data using the Telnet protocol to send to the terminal device, so that the file transfer protocol to obtain terminal equipment for transcoding the string data on the binary data. The file transfer protocol data transcoding binary string data, and then use the Telnet protocol to transmit, to solve the negative problems caused by file transfer protocol Telnet protocol to transmit binary data available directly, achieved in the use of Telnet protocol for remote maintenance, do not need to open a separate line and the corresponding port, you can send binary data file transfer protocol and reception.
