Google Search - Filter by File Type


Let's say you're looking for a PowerPoint presentation on the American Revolution.  If you just search for "American Revolution", your results would look like this:
Rather than searching through the millions of results for PowerPoint files, you can use the filetype: operator.  Just type "filetype:ppt" (notice there's no space after the colon) before or after your search terms and your results will look like this:
The filetype: operator works with lots of filetypes.  Some examples are:

  • PPT- PowerPoint files
  • PDF- Adobe Acrobat files
  • DOC- Microsoft Word documents
  • XLS- Microsoft Excel spreadsheets
  • CSV- Comma-Separated Value files (like Excel spreadsheets)
  • KML or KMZ- Google Earth files
  • SWF- Flash files


Why would you want to find specific files by filetype?  Here's a few ideas for using filetype searches in the classroom:


  • PPT- Find a good PowerPoint presentation to introduce a new topic to your students.
  • SWF- Find interactive Flash files use with an interactive slate or board in your classroom.
  • PDF- Find free graphic organizers, information sheets or other printables.
  • XLS or CSV- Find data files to use for graphing or data analysis.
  • KML or KMZ- Find already created lesson activities for use in Google Earth.  You'll find everything from Shakespeare to geometry to the Civil War... it's not just for geography!

  2. Most computer users will come across files which they don’t have an associated program to edit, view or play them etc, or perhaps you may have a type of file that you prefer to work on in a specific format. File Extensions
