How to Delete Data Backing a Dataset

How do I delete the data backing a dataset?

I've got a ton of datasets our data scientist created. Some of these are good, but most are no longer relevant. These are growing and I want to delete these since they cost money to store.

I think these files located in "blobstore-<UUID>/UI" may be backing files. There are *.csv files.

What are these files located in "blobstore-<UUID>/azureml?

    @Jeremiah Adams Thanks for the question. If you wish to delete the file in Blob storage, you can do that via Azure Storage Explorer/the portal provided you have the appropriate permissions to that storage service.

    This is in fact by design that “unregister” doesn’t actually delete your underlying storage; since an Azure ML Dataset is a reference point to your data in storage, this means we don’t copy your data to your workspace so no extra storage cost is incurred. This also helps safeguard against accidentally deleting files in storage when cleaning up assets in an Azure ML workspace.
