interesting method I came up with for hiding confidential/pr0n/any secret files..
go into tools > folder options >view, and disable the "hide protected system folders" and make sure hiddn folders are visible. Go into your C: drive, and copy any one of the hidden system folders. Paste it into the location of your choice, and rename it to anything you want (suggested something that doesn't look fishy...i.e. "MSOCache"). Load 'er up
No normal person ever has their hidden system files visible. Also, if I'm not mistaken, whenever you perform file searches, it doesn't search hidden system folders.
