Tested on Windows XP Professional SP2 all patched, with Internet Explorer 7
<b>Description:
Using the "Load()" method we can load the content of a file from local machine passed as argument to
this function and then save it into arbitrary location with the "SaveAs()" method.
This allow to overwrite well known files with arbitrary data. I try to pass to the "Load()" method
remote directories (http) but, unfortunately, it accepts only local directories.</b>
