Re: Patching distributed EXE's
Hi Chris,
Write a program that analyzes the difference between two files and outputs a set
of instructions for transforming one into the other - a "delta file". Then write
another program to execute those instructions. Ha ha, easier said than done, esp.
with binary files, but wouldn't it be a good exercise? Something you could
contribute to the archives, too. (This is on *my* to do list - when I get around
to it, which of course may be never.)
