Answer 1

If you have a lot of images or audio files,you might want organize these files well, separate them in different folder instead of placing all of them in app root.

Another situation, you have a project using UIWebView to load local html in your app.You may not want to mess up html, javascript, and css file.

So, maybe organize these file hierarchically would be a good solution.
