It would depend on what they are searching for. If you are carrying something that caught their eye, and they may look just for that. The advantage of the cubes is they can feel it and see it's socks and underwear or whatever and not have to pick through everything. I've had suitcases inspected that I've had the pack it folders in, and they have never gone into the folders that I know of (if they had they never would have put everything back as tight)
