I call it as a reaction to a user selecting a file or a directory. I list its siblings.
The list may be very long. I for one always have many items in the trash. When I hit that I am in for 10-20 seconds of beachball.
You may see this method in action in the Apple provided sample code: SimpleBrowser. You will see that it is way slower to browse the file system than the Finder is.
