Question: Delete all files from the Data Lake Storage Gen2 container

Hi Guys,

I might be blind but I cannot find a simple way to delete all files from the Data Lake Storage Gen2 container.
My use case is static website deployment. I use Data Lake Storage Gen2 as it makes it easier to work with folders.
For the simple NOT Data Lake Storage Gen2 account I can use **az storage blob delete-batch** but if I use it for the
Data Lake Storage Gen2 account container fails with the error below.
Is **az storage blob delete-batch** supposed to work with Data Lake Storage Gen2 based containers?
