If you are writing a clone and are only interested in the file system, there
would be no need to use the shell interfaces at all - you could similate
most of it in pure-python.

If you wanted to use the shell interfaces so that you see everything
explorer does, you would only need to use IShellFolder.  IShellView is only
used if you want to provide your own view *inside* explorer.

If you were hoping to reuse the Explorer IShellView implementations inside
your own application, I think you would have a battle on your hands.

Here is some code that vaguely demonstrates how to use IShellFolder (which I
also just checked into the win32comext\shell\demos directory)

# A little sample that walks from the desktop into child
# items.
from win32com.shell import shell, shellcon

def walk(folder, depth=2, indent=""):
    try:
        pidls = folder.EnumObjects(0, shellcon.SHCONTF_FOLDERS)
    except shell.error:
        # no items
        return
    for pidl in pidls:
        dn = folder.GetDisplayNameOf(pidl,
                                     shellcon.SHGDN_NORMAL)
        print indent, dn
        if depth:
            try:
                child = folder.BindToObject(pidl, None,
                                      shell.IID_IShellFolder)
            except shell.error:
                pass
            else:
                walk(child, depth-1, indent+" ")

walk(shell.SHGetDesktopFolder())
