How to localize special ressource types like sounds, images, movies, html files and so on?

I know I can use NSLocalizeableString() for strings. But how about about other kinds of resources? 开发者_StackOverflow社区I guess there are some kind of language folders where I put that into? Is there an good blog article that describes this?

Right click on any file and choose Get Info. In the General Tab of the InfoView hit the Make File Localizable button, and add a localization. Xcode will copy this file to a location-specific folder in your project.

I use Finder to copy my language specific files into those folders.
