HI @Lakshay Goel​ , thanks for the rapid response!

There are two pages in the documentation, one for HMS:

https://docs.databricks.com/sql/language-manual/sql-ref-privileges-hms.html

which claims "This article describes the privilege model for the legacy Hive metastore".,

and one for Unity Catalog:

https://docs.databricks.com/sql/language-manual/sql-ref-privileges.html

This article describes the privilege model for the Unity Catalog.

READ/WRITE FILES are mentioned in both. What I want to clarify is:

1. Is READ/WRITE FILES a Unity-Catalog-only concept?
2. If not, what is its meaning when working with HMS?
