my question is, how to export game levels as multiple game files that the user cannot access directly, but through the executable game which contains links to open them. here is an example- user123 opens the 'game folder'. then clicks on 'game.exe' . when game.exe runs, it shows 3 levels on the screen. user123 clicks on 1st level.' game.exe' runs the 'level1' game file and user123 plays it. when the level1 is finished, it automatically opens the 'game.exe' again.
i know how to export a single windows executable file, but how to export them into a format which the user cannot run without the main .exe file.
please help
