# Import the DataONTAP PowerShell module
Import-Module DataONTAP

Connect-NcController -Name <Cluster Management IP Address>
# List the contents of the specified directory
Read-NcDirectory -VserverContext <Vserver Name> -Path /vol/<volume name>/<folder name>
Here is an example of these commands in action:
