Abstract: A file transfer method for transmitting a large data file in slices from a sender to a receiver through the Internet on multiple parallel FTP connections uses the restart (REST) command of the industry-standard FTP Protocol to command an FTP server to transfer the respective slices starting with the first byte corresponding to that slice. This method can obtain the same high speed download performance of multiple simultaneous FTP connections without requiring any special software to be installed at the sender end. The “restart” file transfer method can be employed in a batch-processing system for performing file transfers from multiple FTP servers through the Internet in which each file transfer involves multiple parallel FTP connections.
