Okay I get it now. It is impossible to extract all the files from FFX or FFXII etc.. AND rebuild it because there are many hidden files (abot 7000 files) in this game. There is a possibility to extract only the hidden files from this game, but you can´t rebuild it. My intension was to create a multiple disc on a dvd9 with just 2 games. Hope there is someone who could help.
