Saving All Folders in Outlook Express 5

I wish to save my address book and all folders containing mail in Outlook Express 5 so that I can reinsert the info into Outlook 5 on my new PC. I went into C;// drive > Windows > Applications data > Identities > Microsoft > Outlook and put all the .dbx files relating to each folder onto a couple of floppy disks. Is this the correct procedure? When I try to open the files from the floppy disk I get an error reading, but will I be able to reinsert the files into Applications data on my new Outlook? Also, how do I save the address book?
