Question: In a Mission Critical Data (MCData) message store with a folder hierarchy, what occurs to child folders and objects during a folder copy operation?
Option 1: Only top-level folder metadata is copied; child folders and objects are not replicated.
Option 2: All child folders and their contained objects are copied to the new folder location.
Option 3: Child folders are copied, but objects within those folders are not transferred to the new location.
Option 4: The operation only copies the folder structure without any objects, regardless of nesting.
Explanation: This is correct because, as per the described functionality for MCData message stores that utilize a folder hierarchy, executing a folder copy operation results in the duplication of not just the selected folder but also all its contents (child folders and stored objects) to the specified new location. This ensures the entire structure and its elements are preserved in the new copy.
