This is probably a stupid question but I don't know the answer.
I have a laptop that I connect to my home network and hence have the drives open to sharing. Now if I take this to a hotel and log onto their free wi-fi, what's stopping anyone else in the hotel accessing my drives?
As far as I can guess is that we'll all be on the same network and as long as the drives are shared then there is nothing to stop someone else accessing them.
