In software development (including video games), the result of taking the source files of our project and converting them into an executable format is called Build. The generated executable files are optimized to get the maximum performance possible. We can't get performance while editing the game due to the changing nature of a project.

They won't have the textures, audios, and source code files just there for the user to look at. They will be formatted in custom file structures, so in a way, it's protected from users stealing them.
