Excel 2007 : Hyperlink with hidden path & only shows filename?

Fellow Forum Members,
What needs to be changed to this formula:

=HYPERLINK("C:\Root\4x\trades\2009 forward\01 USD-CAD\"&TEXT($A2,"mm-dd-yy")&" "&TEXT($B2,"hh mm")&".pdf")

So that the path shown below is hidden in all of my hyperlinks:

C:\Root\4x\trades\2009 forward\01 USD-CAD

I want the hyperlink to only show the PDF filename. As shown below:

02-12-09 10 00.PDF

The attached Excel file will give you a better idea.

In the past I have seen hyperlinks where the PATH is hiding. How is this done? ANy help will be greatly appreciated. THanks.
