Some people do label directories like that..... (dumbasses can't be clever and hide files in sub-directories of programs or encrypt them, or just password protect a .zip)

Sometimes, when people work on others computers, you don't necessarily browse the hardrive for files, but you can come accross files like

grl11master.jpg
fatherdaughter.jpg
babysit8boy.jpg
and so....

Very disturbing....

Also, people like that usually have a HUGE collection of images (I'm talking 100 to 20,000 images on their drives) Not stumbling accross 1:20,000 is quite difficult...

Think about it......

Trying to get the image program to work (ie: Paintshop, Photoshop)
you click file and look at the bottom of that menu....
"last edited image"
file.jpg
filebig.jpg
c:\windows\image.bmp

you could see it that way or by clickin' on the start menu, then in the documents it'll list some files....
