The sharing of resources, one of its main significance, is that disk file transfer and sharing. Now the FTP to meet the basic needs of users, but the function is not perfect, research file transmission system has very good prospects. Sharing information on the network or file transfer, are based on some kind of agreement are carried out by, FTP was which the people widely adopted for file transfer protocol in the network. Papers described the working principle of FTP and java network programming theory, design a file transfer system based on FTP, use the popular Java language as a system development and use of C / S structure as a document transmission system network structure. System efforts to provide a safe, transparent, efficient environment for file transfer. First of all,papers introduced the concept of the basic file transfer, give a brief descriptiontoJBuilder 2006 development platform and Java language,and then described in detail the basic principles of file transfer,finally a comprehensive document on the network transmission systems and server-client design, technical characteristics and achieve.
