The present invention provides a system for handling and transmitting a file over a communication channel wherein the file may be adaptably compressed to improve throughput. The invention also provides for a method of recovery in the event of a communication failure. The file may be encrypted while it is being transmitted. The compression and transmission may occur while the file is being written, so that the receiving location receives the data in near real time.

[ What is claimed is:] [8.] A system for managing and transmitting a file having a degree of compressibility and a plurality of buffers over a communication channel comprising:a.) a communications channel having a physical bandwidth;b.) a transmitting processor;c.) a receiving processor;d.) a means to determine transmission throughput;e.) a means for compressing the file by compressing a first buffer to a first degree of compressibility, compressing a second buffer to a second degree of compressibility, transmitting the first and second buffers and determining a relative throughput, based on the relative throughput, compressing a third buffer to a third degree of compressibilty;f.) a means for compressing the buffers of the file in a stream in real time while the file is being written;g.) a means for transmission of the file;h.) a means for maintaining a received location of the transmission within the file;i.) a means, responsive to an transmission interruption and subsequent resumption of transmission, for communicating the location of the data last received prior to the transmission interruption;j.) a means for encrypting the file in a stream before and during transmission; andk.) a means for decrypting the file after receipt of transmission.
