File extensions

Is there an organization that registers, collects, tracks, checks, validats files' extension. I mean is there something similar on Windows to how Apple registers and tracks file types on Mac OS?
Or, at least, how do you check if a file extension you plan to use is not occupied by some other program?

There isn’t. This is why every other program seems to use .dat for something. On the other hand there isn’t much of a reason to stick to just three letters for the extension nowadays and if you use a longer one you can probably avoid a clash.

Hmm. IMHO there are some central place for registering MIME types like "plain/text". It could be that exatensions are placed there also :)

Why do you care if a file extension you plan to use is also used by some other program?

It is possible to end up with situation when a program tries to open files that cannot be opened (as they are created with different program).
