I once tried hardlinks on Windows (not in a RB context), but I can't remember whether that was on a dir or on a file (POSIX only supports hardlinks on files IIRC). Anyway, I don't think Windows CE supports hardlinks and even if, most devices have their data files on a FAT partition I believe.

Of course, but that would introduce extra code in RB (I was mentioning an "easy" solution).

Now thinking about it a bit more, Android also has its user data on a FAT partition so symlinks wouldn't work either. So you're pretty much forced to emulate the behaviour in the RB filesystem code.
