Remove sharing

[Callumpy]

Forgive me if I've missed it.

Is there a way to remove sharing from files, currently it seems files are shared indefinitely and I worry that my link could get spread around and abused.

Edit the "db.json" and remove the link. Don't think there is another way atm.

It would be very useful to implement something that removes sharing files.
