Question: What happens to child folders and objects within a folder when a user deletes an existing folder in their MCData message store, assuming a folder hierarchy structure?
Option 1: Only the top-level folder is deleted, while child folders and objects remain intact.
Option 2: Child folders are deleted, but objects within those folders are preserved in the root directory.
Option 3: All child folders and objects stored within the deleted folder are also deleted.
Option 4: The deletion operation triggers an automatic backup of all child folders and objects before they are removed.
Explanation: In the context of MCData message store with a folder hierarchy, deleting a folder has a cascading effect. This means that not only is the specified folder removed, but also all its contents, including any subfolders (child folders) and the files or messages (objects) they contain. This ensures consistency in the storage structure but also implies that such an operation should be undertaken with caution to avoid unintended data loss.
