What are the root directories?
Databricks historically used directories in the workspace root directory for common storage locations. Most of these locations are deprecated.
/Volumes
provides an alias for path-based access to data in Unity Catalog volumes. See What are Unity Catalog volumes?.
/databricks-datasets
/user/hive/warehouse
/FileStore
What is stored in the /databricks-datasets
directory?
The /databricks-datasets
directory is available on all access mode configurations unless custom workspace permissions set by workspace administrators prevent access.
Databricks provides a number of open source datasets in this directory. Many of the tutorials and demos provided by Databricks reference these datasets, but you can also use them to indepedently explore the functionality of Databricks.
