What is the .nk2 file extension?
The file extension .nk2 is used to represent the AutoComplete file of Microsoft Outlook 2002 and later. Outlook is a popular email software that forms an integral part of the Microsoft Office suite. The .nk2 file falls under the miscellaneous files category.
The AutoComplete file is an important part of Outlook. It stores the names of email addresses to which you have previously sent email. In addition to storing email addresses, AutoComplete also stores the names of people to whom you have sent earlier emails, the email type and other information is also stored in this file. This file is the one which makes it possible for the AutoComplete feature to help you with email addresses when you type in the To, Cc, or Bcc fields.
The AutoComplete feature uses the information stored in the AutoComplete file to help you with email addresses. For instance, let’s say I send an email to firstname.lastname@example.org. Now, the next time I type the letter ‘m’, the email address email@example.com will automatically appear, along with other email addresses that start with letter ‘m’ to which I’ve sent an email using Outlook.
How to disable the Outlook AutoComplete feature?
If you want to turn the AutoComplete feature off, just perform the following simple steps:
- Open Outlook, go to Tools menu, and click Options.
- Next, click Preferences.
- Click Email Options and then click Advanced Email Options.
- Clear the checkbox before Suggest names while completing To, Cc, and Bcc fields, and click OK.
What is the location of the AutoComplete file?
By default, the file is located in C:\Documents and Settings\Username\Application Data\Microsoft\Outlook.
The AutoComplete file is profile specific; what this means is if you have multiple Outlook profiles, there will be one AutoComplete file for each profile. Also, these files are saved as the profile name of Outlook, followed with the .nk2 extension.
