It’s a staple of cartoons and stories about people in prison - but did it ever really happen?
here are somethings that have been smuggled… http://www.mirror.co.uk/news/top-stories/2009/01/07/prison-smuggling-mirror-co-uk-s-top-ten-best-ways-to-get-things-into-jail-115875-21023420/
The copy/paste function does not seem to work well on backed goods. I usually hide files in a folder with a boring name, like “Budget 06-07”
They do that kind of thing on Prisoner (Prisoner: Cell Block H) all the time. Of course not when Vera or Joan are on duty 
That’s why you should always make a good bake-up of your files.
