Abstract
The invention belongs to computer data file processing field and in particular relates to a file transfer and management method. 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. In the method, special file name servers uniformly generate temporary file names, thus avoiding overlap caused by naming conflicts. The method also avoids directory confusion caused by disk mapping errors and can prevent uploading, acquisition and deletion of the files through devious ways, so the method has good security and confidentiality. The method 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.
