Breaking Windows recently listed a few effective Google search strings that can be used to locate all sorts of shared media files on various servers. For instance, to locate MP3 files, try copying this string into a Google search:

“parent directory ” MP3 -xxx -html -htm -php -shtml -opendivx -md5 -md5sums

Or searching for MS ISO’s? Try:

inurl:microsoft filetype:iso

It’s amazing what you can find even without P2P software, which is usually loaded with tons of spyware.

Of course, this information is for educational purposes only.
