 The URI may include the `*` character to match any sequence of characters, allowing `OPENROWSET` to pattern-match against the URI. Additionally, it can end with `/**` to enable recursive traversal through all subfolders.

+You can use `OPENROWSET(BULK)` to read data directly from files stored in the Fabric OneLake, specifically from the **Files folder** of a Fabric Lakehouse. This eliminates the need for external staging accounts (such as ADLS Gen2 or Blob Storage) and enables workspace-governed, SaaS-native ingestion using Fabric permissions. This functionality supports:
+- Reading from `Files` folders in Lakehouses
+- Workspace-to-warehouse loads within the same tenant
+- Native identity enforcement using Microsoft Entra ID
