I'm not sure what Microsoft is thinking, but it does not own the *.XML extension! What total bastards! I was browsing around the iTunes folder, and Office 2008 had, without my permission, assigned all *.XML files as "Microsoft Word Documents." That's just ridiculously annoying. It opens in TextEdit, but the principle of the matter is that it has no place to assign a generic markup document as its own. How do you fix this? I want to go through a list of file associations and freaking remove Microsoft from the unnecessary types. This happened in the Windows world too. Microsoft Office would create 20,000 file associations, regardless of necessity, and it was just downright annoying.
