def create_folder(kwargs=None, call=None):
    '''
    Create the specified folder path in this VMware environment

    .. note::

        To create a Host and Cluster Folder under a Datacenter, specify
        ``path="/yourDatacenterName/host/yourFolderName"``

        To create a Network Folder under a Datacenter, specify
        ``path="/yourDatacenterName/network/yourFolderName"``

        To create a Storage Folder under a Datacenter, specify
        ``path="/yourDatacenterName/datastore/yourFolderName"``

        To create a VM and Template Folder under a Datacenter, specify
        ``path="/yourDatacenterName/vm/yourFolderName"``
