Can I use library abstractions in python?

I use:

for root, dirs, files in os.walk(rootDir):

to navigate directories. Everything is awesome. However, I am running Windows 7, which of course has an abstraction of the library. So, for example, an image library can map to c:\users\meand is c:\users\share there a way to use this library abstraction using python?

If I’m not mistaken about how this function works (I actually don’t have a Win7 window in front of me), you will have to turn to the Windows APIs to access the libraries.

        pythoncom.CLSCTX_INPROC_SERVER, shell.IID_IKnownFolderManager)
libs_folder = kfm.GetFolder(shell.FOLDERID_Libraries)
libs_path = libs_folder.GetPath()

for lib_file in os.listdir(libs_path):
    if os.path.splitext(lib_file)[1] == '.library-ms':
        print lib_file
        i = shell.SHCreateItemFromParsingName(os.path.join(libs_path, lib_file),
