If you are actually a computer enthusiast and not just as appliance operator, you probably want to UN-Hide everything anyway.
I found a great little script to set all files to UN-Hidden. I use that a lot!
That and Take Ownership are two scripts I use on every PC I set up.
Like most scripts that I use, there is an UNDO script too.
I was playing around on my Windows 7 HD last night and thinking about this thread.
I tried finding things with the old DOS "dir" command and for the most part it worked pretty well. (for one specific file, anyway )
I just opened the 'Command Prompt' and reset the path back to the root and then typed in the old DOS command
dir filename /s
and I got a listing of all the files with that name and their paths.
But there's a glitch of some kind in W-7 ..... because when I typed in
dir *.tmp /s
everything went crazy scrolling file listings on and on, over and over with very long paths that don't even exist. Try it and you'll see what I mean. I had to ABORT the scan or it would probably still be running.

I'm using Windows 7, Ultimate 64. I've not had a 32 bit version of Win-7 to try these things on, so I don't know if it would work differently.
Interesting thread.
