IShellFolder

The IShellFolder interface is used to manage folders.

When to Implement
Implement IShellFolder for objects that extend the shell's namespace. For example, if you create a separate name space that requires a rooted Explorer; or if you install a new name space directly within the hierarchy of the system name space.Only you know anything about the contents of your name space so you are responsible for implementing everything needed to access your data.

When to Use
Use IShellFolder when you need to display or operate on the contents of the shell's namespace. Objects that support IShellFolder are usually created by other shell folder objects, with the root object (the Desktop shell folder) being returned from the SHGetDesktopFolder function.
