Smart Folder

A folder that contains a list of files that have something in common. You specify the criteria for the items you want added to the folder, such as the type of file, the date a file was opened, or the contents of a file. For example, if you like to bake, you could create a Smart Folder that has all the Pages documents you opened in the past year that contain the words cookie and recipe.

As you add, change, or delete files that meet the criteria, the list is updated automatically.
