What I would do (and continue to do) is use the "Export" function of Outlook 97/98/2K/XP to keep all of my stuff. Just go to "File>Import and Export" and then select "Export to a file". You will be presented with several options to choose from. If you use PST, that's a proprietary file format for Outlook, it will preserve all subdirectories and can be imported later (this was the file that you were "backing up" using your other method) back into Outlook. If you use CSV format, that can be read in Notepad, Excel, and can be imported into various contact manager programs/databases. Take a look at it and give it a whirl.
