Steps to Export Autocomplete Cache to Another Computer

You may hear about NK2 file which is by far one of the most convenient and the smartest option for Outlook users. As you enter new contact (email address), the NK2 file automatically stores the contact whether or not it has been added to the address book. When you write the following email address to the contact fields (To, CC or BCC), it allows you to auto-complete the email address. You don’t need to remember the whole email address of your contacts. But relying upon the autocomplete entirely can be risky. You can lose them. Add each address to the contact list.
