PC Email Errors
In this article, we will discuss the following topics:
• The name and purpose of three common file types associated with e-mail client programs, such as Microsoft Outlook.
• Steps to resolve common file type errors.
Common e-mail file types
.nk2 file extension and its purpose
An .nk2 file is commonly referred to as Outlook’s AutoComplete file. Outlook is a popular e-mail program from Microsoft. The .nk2 file format was first introduced with Outlook 2002 and since then has become an important component of the Outlook application.
The .nk2 file is used by Outlook to store details about the e-mail addresses to which you have sent e-mails. Outlook’s AutoComplete feature works in conjunction with the .nk2 file to help a user when he/she types an e-mail address or recipient’s name in the To, Cc, or Bcc field. For instance, when you type a letter, say ‘a’ in the To field, the AutoComplete feature refers the information stored in the .nk2 file and displays all the e-mail addresses starting with the letter ‘a’ to which you have previously sent an e-mail.
.idx file extension and its purpose
.idx files are index files that are used by various applications, including Microsoft Outlook Express. The .idx files store an index of mail messages and are used when you import old Outlook Express mailbox into Outlook Express version 5 or later.
.nick file extension and its purpose
A .nick file is commonly referred to as an Outlook 2000 Nickname file and these files allow you to designate a string of characters as a nickname of an e-mail address.
Resolve file type errors
In case you receive an error, such as ‘Windows cannot open the file’ when you try to open a file, then either the program required to open the file is not present on your system or the file in question is corrupt.
To fix the issue, you need to identify the program with which the file opens and install it on your computer. If the error persists or you already had the required program, then we recommend you use a reliable file extension repair program to help you open the desired file.
In case the file type error occurred while opening an application then plausible causes include: a poorly installed application, malware infection or registry errors. To fix the error in such cases, perform the following steps:
Step #1 – Uninstall and re-install the program with which you are receiving the error
Using the built-in Add or Remove programs utility, uninstall the application that is generating the error and reinstall it. If the error persists, move to the next step.
Step #2 – Perform a malware scan
Update your security software with the latest malware definitions and security updates and run a malware scan on your entire computer. To ensure all residing threats are aptly removed, you may run the malware scan twice.
Step #3 – Perform a registry scan
Using a professional registry cleaning software, perform a registry scan to fix registry errors and restore the integrity of the data stored in your registry.
