A smart folder is like a saved search; it shows shows records in the library that match certain criteria. EagleFiler has four built-in smart folders: Recently Added, Recently Modified, Unfiled, and Untagged. This command lets you create your own smart folders.
You can organize smart folders into folders. To do this, select a smart folder and choose New Folder…. Then re-arrange the smart folders using drag and drop.
Creating and editing smart folders requires Mac OS X 10.5 or later; however, once created, the smart folders can be used with Mac OS X 10.4.
