laptops airports....

Find the folder and delete the lot before going.

honestly, unless you are Edward Snowden (or the partner of the Guardian journalist who leaked his material) nobody is going to look at the contents of your laptop. In a decade of frequent work travel with laptop, including to countries like Saudi Arabia and China, nobody has ever asked to check the contents of mu hard drive. nor have i ever heard of this happening.

Ok, thanks.
Nobody looked.

But it is possible to click on a video clip, watch it (like on YouTube), and find months later that some clips were not streamed, they actually downloaded themselves onto a folder somewhere hidden in the computer...
