Say you were interested in searching for information on automotive dealerships. After typing in your key words -- in this case, automotive dealerships -- add filetype:ppt. This tells Google to restrict the search to a specific filetype, ppt, which is the filetype extension for Powerpoint. Google then searches for and returns results that are ONLY Powerpoint files. Other filetypes, such as html (hyper-text markup language), pdf (Adobe portable document format), and doc (the file extension for Word documents), are deliberately EXCLUDED. This is a quick and easy technique to zero-in your Google searches on Powerpoint files and an underrated way to uncover new and fresh online information on virtually any topic.
