I found the utility xdelta. Pretty cool. Allows you to compare 2 file and create a compressed delta file. The delta file has MD5SUMs of both files. The xdelta patch option will apply the delta file to create the new file.
This should allow you to send only what changed in a file to a user instead of the whole file. Regards, Jeff -- Jeffrey C Barnard Barnard Software, Inc. http://www.bsiopti.com Phone 407-323-4773 Fax 407-323-4775
