You give a name to a note when you create it, and you can change the name of an existing note. See Create a Note and Rename a Note.

To specify that the note should be contained in a directory, add a qualifying path to the name. For example, to put a note named note1 into the Demo directory, specify its name as Demo/note1. To move that note to the Test directory, rename it as Test/note1. If the directory doesn’t exist, Oracle Big Data Manager creates it.
