Whatever you think would be the best... I have no clue on this really, but I can learn as I go.malodorous101 said:xdelta3 seems to actually create slightly larger patches using the same source/target with the same flags. You can reduce the size by about 10% if you use secondary compression -S djw but it's not really that significant, unlike some of the methods Noitora mentioned which will save ~98%.
I just want something that is simple for people to use... If that means the patch is 32MB, fine, its not THAT big.
If i can get the file size down and still keep it easy to use, then I'd love to hear about it, so give me a recomendation.
