Jimmy Ruska, a 21-year-old American, has posted a video on YouTube explaining how to use Google’s search engine to download music and ebooks for free. The video shows users how to do an "index of" search and how to direct Google's search engine to locate files from unprotected computer systems, such as university systems. “A lot of students use the web-space given to them by their university to share music with their friends,” said Ruska.
Ruska's formula also worked at Yahoo and other search engines as well. According to Ruska, music files could be downloaded this way far more quickly than from peer-to-peer file-sharing networks.
The video is potentially embarrassing for Google, which owns the YouTube video-sharing website. In order to prevent illegal music download, Google has long since disabled functions that were previously used to search for MP3 music files.
I couldn't find that video in youtube. Youtube might have removed it. However, I found it at another web site: King Nutter
Jimmy Ruska actually created a web site to help people download mp3, ringtone, and pdf from Google:
Jimmy's "index of" trick:
(For example: you want to search for a mp3 song called "No one knows".)
1) Go to google.com
2) Type the following in search box and perform search.
intitle:"index.of" (mp3|mp4|avi) No.one.knows
3) If you don't want web pages, type the following in search box and perform search.
intitle:"index.of" (mp3|mp4|avi) No.one.knows -html -htm -php -asp -cf -jsp
4) If you want to search for pdf in university sites, type the following in search box and perform search.
site:.edu intitle:"index.of" pdf
5) If you want to search for calculus pdf in university sites, type the following in search box and perform search.
site:.edu filetype:pdf calculus
Create shortcut in Firefox to perform the above search:
1) Perform step #3 in "index of" trick.
2) Copy the result url
3) Press "Ctrl-B" to display the bookmarks page
4) Add a bookmark by right click and select "New Bookmark..."
Name = directory index
Keyword = music
Location=(paste url from step #2; scroll to the word "No.one.knows" and replace it with "%s")
5) Click Ok in the New Bookmark window.
6) In Google search box, type the following and perform search.
7) You'll get same result as the result in step #3 of "index of" trick.
