Hi @giuseppe_esq. I'm currently exploring the free edition too!

To answer your question about a Mount Script with a notebook, I've a feeling this won't be achievable (could be proven wrong though). 

I looked at the documentation on the Free Edition limitations/compute: https://docs.databricks.com/aws/en/getting-started/free-edition-limitations 

& the all-purpose compute is serverless. And according to the limitations on the serverless documentation:
https://docs.databricks.com/aws/en/compute/serverless/limitations 

I appreciate that this is talking about AWS , but I think the same will be true for Azure. I still think it's worth trying, though 😂. 

I'll answer your other question in a subsequent post.

All the best,
BS
