Why doesn't Devonthink keep the original docx or doc files?

Without being nasty, this is one of the worst things I’ve noticed while testing the product. What the hell is the point of having a Document Management System if it changes the format so much that the document cannot be recognised as the original document? I can understand needing to make a RTF copy, but why not import the original format as well?

While testing it I imported a whole lot of documents, and then suddenly noticed I need to keep the original folders I had imported because it wasn’t maintained original formats. That means the original files can potentially be deleted whilst there is still a reference in Devonthink.

Maybe someone can tell me something I’m missing here, because other than that its a really nice product, but this is sales killer.

A longstanding complaint, and one that will be resolved very soon.
