Locking files after a while

There is a functionality that i need but that I had no founded anywhere.

I’d need to be able to send some impress documents to someone, but I’d like those documents were outdated after two or three weeks with some expiration trigger or whatever.

I’d rather no to think that my work is being shared over and over out of my control, only because there are some disrespectful people.

Does someone know if this is possible in some way?

Thanks a lot

I have not heard of how you could do it. If you want to be sure that it does not slip out of your hands, you should not give it up either. Unless you have absolute trust in someone.

But it seems strange that you ask with your question just in a community in which free knowledge is propagated.

I wish you much success anyway.

Of course I agree with free knowledge sharing, but imagine you were a student and you don`t trust in your teacher. And after a while you read your own work owned by your teacher in a science magazine.

As well as you, I think in sharing knowledge. I worry about people who don’t share and are always profiting from others.

Thanks for your point.
