Abstract

A file transfer system including a client and a server capable of updating portions of the file stored on the server. The system is capable of uploading portions of a file before the file has been specified at the client side. The files are stored in raw at the client and the server, which preserves the block list mapping. The file transfer protocol is capable of compressing and encrypting transferred data. As a result, the partial file writes are possible while maintaining current bandwidth usage. The write request data structure is provided with additional features in the form of flags and fields to provide reliable transmission of partial file data.
