The .NK2 file is a container used by Microsoft Outlook to store the contact names and e-mail addresses named in it. It is an alternative to using the TXT or CSV (Comma-Separated Values) file formats.
This list of contacts, also known as nickname list, is stored with the contact name and the associated e-mail address information within Outlook's mailbox. When users type a name into the "To:" field on the Outlook compose window, the program utilizes the nickname list to auto-populate the contact's e-mail address. The NK2 file is Outlook version specific; for example, Microsoft Outlook 2002 creates a file with a .NK2 extension, while Outlook 2007 utilizes an NKTM extension.
Uses
The NK2 file enables users of Microsoft Outlook to quickly enter contact information into emails, without having to manually enter email addresses. The.NK2 extension is stored within a user's mailbox and is accessed every time Outlook is opened so that it can maintain its cache of contacts.
Similar File Extensions
Other similar file extensions to the .NK2 file are the .NBF, .NBU, .NCF, and .NDB.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .NK2) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .NK2 extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .NK2 file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .NK2 extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .NK2 extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .NK2 file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .NK2 file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .NK2 file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .NK2 file) will be extended to the maximum.
It is also good to check
- if the .NK2 file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
