Expose the local machine hard drive in a web page

In some circumstances, you may simply see a blank white box above. In other cases, this box reveals the file and folder structure of your local hard drive.

You may be forgiven for thinking that this web page has hacked into your local machine, and that we have access to your files and folders.

However, this is not so. It is just a trick, created by an inline frame (IFRAME) tag, as follows :-

    <iframe src="file:///C|/" height=150 width=90% marginwidth=0 marginheight=0 scrolling=no frameborder=0 vspace=2></iframe>
