Any way to do that?
No. Not in the way you probably expect (like a disc folder).
Folders in a Blob storage are virtual and "created" when the blob is placed.
Lets say you want to put a file called "intake.docx" in a folder "project x" inside the Azure Storage Container. Simply name your file "project x/intake.docx" and you have created a virtual folder that contains that file.
So you can have "folders" of which you can query the contents (Get all files starting with <folder name>) but you can not have empty folders. Doesn't really matter for the SDK since the Get all we just used will result zero files and that is exactly what you should expect even when you have an empty folder.
Hope this clears things up a bit.

ps: I found a nice blog that seems to go a bit deeper into this. I didn't read it fully though: https://fsou1.github.io/Nested_folders_with_azure_blob_storage
