Abstract
The invention belongs to computer data file processing field and in particular relates to a file transfer system based on FTP protocol. Currently, when people transfers files between a client and a server end through FTP protocol, the people only needs to know the user name and the password, so file management safety is poor. The system is added with a special file name server on the basis of the FTP client and the server, and the special file name server generates temporary file names uniformly, thus avoiding overlap caused by naming conflicts. Meanwhile, the system can prevent directory confusion caused by disk mapping errors and can prevent uploading, acquisition and deletion of the files through devious ways, so the system has good security and confidentiality. The system can make full use of the FTP protocol to ensure reliability and break-point resume of the transfer of the files, thus reducing work load and improving work efficiency.
