Getting a reference to a CloudFileDirectory in Azure Automation and PowerShell Runbooks

Question

I'm working with Azure Automation and PowerShell Runbooks and I need to get a reference to a CloudFileDirectory. The directory already exists, and does not need to be created. The only way that I have found to create this reference is to using New-AzStorageDirectory. This looks like it will create the Directory. If this is the only way, how do I call this function to get the CloudFileDirectory? If there is another way please let me know the syntax to call the necessary function.
