IPersistFolder 

The IPersistFolder interface is used to initialize shell folder objects.

When to Implement

When implementing a shell namespace extension, specifically IShellFolder113Z9WE, you need to implement this interface so the folder object can be initialized this is how the folder is told where it is in the shell namespace.

When to Use

You don t use this interface directly. It is used by the file system implementation of IShellFolder::BindToObjectJUR8KZ when it is initializing a shell folder object.
