How can I easily find a shared folder if I don't know what aggregate and volume it is on?

Answer:

Go to the "View" menu and choose "All Shared Folders". This will display a new entry in the tree named "All Shared Folders", which shows all the folders and qtrees on your filer which are shared, regardless of which aggregate and volume they are on. This is an easy way to find a folder or qtree if you don't know what aggregate and volume it is on.
