No, and there can't be one, because not all OS store such information.

If you think of Linux: There is no central repository for such information. It depends on the desktop environment you use. And of all possible desktop environments, only a few have some kind of repository. Of course, not all desktop environments store the required information in the same place and in the same structure.

    adamk++ for making the impossible possible with File::HomeDir. I should've read the question more thouroughly - my answer was about the directories to store My Images, My Music etc., not programs to open such files.

    But how do those OS achieve the magic of double-clicking?
      each in their own way that they choose, obviously :)
