I'm aware of the DS. However, the only thing I could think of is to
read it, modify it and reference the new file. However, this is not a
very good method if more than one extension does that because they
would all just know the original DS. Isn't there a way of adding to the
DS once it has been parsed and loaded into memory? That would solve my
problem perfectly. :)
