Help restoring data

I am fairly new to this so please bare with me  :smiley:  I needed to reinstall Windows XP on my computer.  I had the WD world drive back up everything before I installed XP.  I was able to copy the “my documents” folder to the computer but I am having trouble finding and copying the Outlook favorites and Outlook Express email and address book.  Can someone help me locate that information (if it is backed up) and explain how to find the right folders in XP to copy it to?  Thanks for your help.
