So basically, I’ve recently tried to publish a game on a website, but it can only be one file. I know it’s possible I just dont know how. How can I save final game and the game info folders all in one file.
So the reason you want it to be in one file is to easily distribute it via a website? If so, why don’t you pack it in an installer. (For windows a .msi, I don’t have experience with Mac).
This way the user downloads a single file which will extract your game in a specified directory, most installer tools also give you full control over pre-install actions or post-install actions you would like to execute.
Take a look at these Google results for more information.
What formats are supported? If you cannot get the correct format, then it won’t work. Read the manual for the website.
