A paper folder can also be used to storage data, therefore the folder image can be used as a metaphor to facilitate the undertanding of the hard drive use.

It could be a file folder or a shoebox or anything you like, but I think it's good to keep each idea on a separate piece of paper.

First, open your binder, set your loose leaf paper between the dividers. Put your folder in the front so that you can put worksheets or loose papers.
