Step 1: Open ‘Search For’
The Search For option is always at the bottom of your sidebar. Clicking the little arrow next to the option will reveal its drop-down menu, and from here you can select the search parameter that you want.
Step 2: Lost and found
When you’ve found the item you were after, you can see a preview using Quick Look or the Cover Flow view. At the bottom of the window it’ll show you the folder path for the file, so you can note its location.
