Data sharing method between network system and hosts

[0019] figure 1 It is a schematic flow chart of an embodiment of the data sharing method of the present invention, which is based on the network system of an embodiment shown in him 2. The network system shows the connection relationship between the various hosts, such as figure 2 As shown, the network system includes multiple hosts, and further, the multiple hosts are divided into a first host 21 and a second host 22 according to whether the FTP server is turned on or not, and the two are connected via the Internet. Among them, the first host 21 is a host that starts the FTP server, which can share its stored files with one or more other hosts in the network system, and the second host 22 is a host that can share data stored by the first host 21.

[0020] The network system can realize the connection between the hosts through a predetermined local area network. Like most Internet services, the network system can also be regarded as a client and server system. The first host 21 that
