Hi @Chris Nawara​ , The two documentations talk about data governance. The concept of data governance is not exclusive to Unity Catalog. The difference here is that Unity Catalog helps you in implementing Data Governance at a much more granular level and better than HMS. So, to answer your questions

  1. Is READ/WRITE FILES a Unity-Catalog-only concept? No
  2. If not, what is its meaning when working with HMS? You can read/write a file with both HMS and UC. But how the data governance and security works in two is the difference.
