Date updated: December 20, 2024

The nk2 file extension is associated with Microsoft Outlook, a personal information manager, which is part of Microsoft Office, developed by Microsoft Corporation.

The *.nk2 files are used by the Auto-Complete feature. Outlook's auto-complete feature attempts to be helpful by suggesting email names that are similar to what you're typing. A couple of keystrokes, an auto-complete suggestion, and you don't have to type the entire email name every time. Seems both simple and handy.

The *.nk2 file is hidden by default. The older versions of Microsoft Outlook were using the nick instead.
