High-level operators also have an associated view of the data map where the suboperator productions will be checked against. Files aid organization. The only place where user's can add file entities is under the elaborations folder. An elaborations file is automatically created for you under a high-level operator. Note, this will also work for operators.
Folders are also organizational aids.
There are always two, elaborations and all . All is a place to put operators that don't belong in any particular place in heirarchy because they can fire in all states. Elaborations is a folder that contain files with productions that relate to the top-state, fire in all possible states, or other productions that do not fit well within the hierarchy. The rule editor allows you to edit the actual productions associated with operator or file. It provides basic text editing facilities.
