In fact, what standards are you using to name them?

I have another suggestion, that is to use the language codes in Windows Vista's and Windows 7's MUIs.

If I am not mistaken, IETF language tags are used to name the interface string files.

Somehow I don't see the point in doing so, as openBVE doesn't use MUI-style localisation, but anyway, as far as I can tell (I'm using XP), the language folder names of MUI applications are IETF tags, too.
So in fact, your idea is already implemented.

Not to mention that it is really irrelevant how the files are named. The user selects the language from a list where the name of the language appears, not the code.

But I am talking about that, even when users select from the list, the languages files still need names.
Would you take the Simplified Chinese to be "asdfghjkl.cfg"?
No! You will name it as "zh-cn.cfg"!
So "zh-cn" is the language code.
