The present invention provides a system and method for efficiently transferring files using file differentiation. In architecture, the system includes a client device with a device file, a server device containing an original file and a revision file of the original file, and a delta file that identifies only the changes between the original file and the revision file. The present invention can also be viewed as a method for efficiently transferring files using file differentiation. The method operates by (1) providing an original file; (2) creating a revision file of the original file; and (3) generating a delta file that identifies only the changes between the original file and the revision file. |
