I think there are two sides to this.

Yes, on the one hand they can't ask you to incriminate yourself ...

But on the other hand, if they have a search warrant, don't they have the right to search your files?

It's like having a safe in your office ... are you allowed to withhold the key to it from law enforcement officials if they have a search warrant?

I'm no lawyer, so I don't have the answer, but it's an interesting question.
