New folder Creates a new folder. Folders are used to structure the models hierarchically. Thus, if your model consists of say three submodels, you can create three folders, and store the submodels inside these folders. Since a folder can contain other folders, you can have submodels within submodels. The hierarchical depth of a model is limited only by the amount of memory. To see the contents of a folder, you open it by double-clicking it, just like you do with folders in “Finder”. The “New folder” button is not present in the “Edge table view toolbar”.
