Get imagenet with synset folder structure

[JohnFarl]

I need to get all the subclasses of the branch with the folder structure of synset e.g. If I want to get geological formation class, the result should have a main folder for geological formation and this folder should have subfolders for all subclasses like beach, delta cave etc. and each subfolder, in the same way should contain inner subfolders for the classes contained in its category.

How could achieve this with your tool?
