To find a lot of interesting stuff on Google Drive, Google Dorks can be of assistance. Various search terms can find interesting files and information that people have stored on their Google Drive.
This is the search term: site:drive.google.com [your search term] -“Whoops!”.
How to find new open directories: http://palined.com/search/ or http://www.filechef.com/, search for what you’re looking for, though sometimes you get better results by leaving the filetype on default (Palined) and Other (Filechef). (The -“Whoops!” gets rid of the results that are removed because of Google’s Terms of Service.)
