If I had anything I didn't want people to see on my computer (I don't) I'd just put it in a scary sounding folder, like, "TOSHIBA SYSTEM FILES."
That's my research folder. :P
Brilliant folder name.
Imagine the embarassment you would feel if someone accidently dug up your secret folder full of pony research.
Who honestly needs 20,000+ images of pony research?
