A great Google hack that can be adapted to search for any file type that you need. Just use the examples below, typing the bold text into Google’s search box to find whatever file extension you’re looking for, then include as many keywords as you need to narrow down your search.

Example 1 - searching for any mp3’s with “the orb” somewhere on the page:
-inurl:htm -inurl:html intitle:”index of” mp3 “the orb”

Example 2 - searching for a pdf to do with programming in C#:
-inurl:htm -inurl:html intitle:”index of” pdf “programming C#”

Example 3 - searching for a jpg image of a mountain view:
-inurl:htm -inurl:html intitle:”index of” jpg “mountain view”

As you can see, it makes Google an even more useful resource for tracking down files you would otherwise spend hours trying to find. Just adapt the search string and search for what you need.
