Help!!!My wife found my porn pics!!!!

God damn it, my wife found my porn pictures last night! There are over 2GB  of Hight-Definition ones.
It kills me! She had a bad quarrel with me and said that if these kinds of pictures would appear in my computer once again, She'd have a conversation with the lawyer. To becalm my wife, I had to delete all the pictures in front of her.
But luckily, with the recovery tools, I successfully recovered most of them.

But how to keep these pics secure is a tough issue. Changing the file property to "hidden" will not work.I don't wanna compress them wit, as it is too complex and time-consuming. Oh God, the hardest job in the world is to be a married man. I love my wife more but I need these pictures. I have collected them for long. It is a pity to lose them, because the bad economy has deprived me too much of leisure pleasure
What should I do, guys? Is there any tool or method can keep them secret permanently?
