Partial File MD5 Verification

This invention concept pertains to MD5 verification of partial files, such as for FTP or SSH file transfers, to verify the partial file that was not transferred completely, to determine if any part of the file was not transferred completely, such as due to file corruption, on the client computer, or on the server computer, compared to the server computer, or the client computer system. This would allow for partial re-transfer of the partial file, or even re-transfer of part of a completely transferred file, rather than complete transfer of the entire file again.
