Find all the files on your Mac of a particular type or extension

Sometimes the easy things seem hard until you know the knack.

- GLENN FLEISHMAN

I find myself regularly needing to limit a search to a particular kind of file, like images or mail messages. Or I know that I have a limited number of files on my Mac of a certain kind, like those created by OmniGraffle, and I can't remember the file name-just that I created it in OmniGraffle! You can use Spotlight in the Finder or create a smart folder for repeated uses that will fit this need. In the Finder, press Command-F to bring up a new window with the focus in the Search field.
