You can easily use Google to find thousands of Mp3s, Ebooks, Images and Movies that are stored in unprotected directories on the Internet. By the term "unprotected" we are not just referring to "not password protected" directories but also to directories that don't have an "index" file. If you try to access a non-password protected directory that does not have an index file, the webserver will show you a listing of files that are within that directory.
Examples
Find any movie files in AVI or MPG format
[-inurl:(htm|html|php) intitle:"index of" +"last modified" +"parent directory" +description +size +(mpg|avi)]
Find audio files in WMA or MP3 format
[-inurl:(htm|html|php) intitle:"index of" +"last modified" +"parent directory" +description +size +(wma|mp3)]
Find images files in JPG or PNG format
[-inurl:(htm|html|php) intitle:"index of" +"last modified" +"parent directory" +description +size +(jpg|png)]
How To Be More Specific ?
Find any types of files about Jennifer Lopez
