What is an XNK file?
An .XNK file is an Exchange Folder Shortcut. Microsoft Exchange and Microsoft Outlook create these files. The file contains a link to a specific public folder, mailbox, or document on an Exchange server. Users click the shortcut to open the target folder quickly without navigating through complex server directories.
How to open XNK files?
You typically open an .XNK file using Microsoft Outlook. However, modern versions of Outlook disable .XNK files by default for security reasons. Because shortcuts can point to harmful locations, Microsoft blocks them in newer software updates. You can use a basic text editor like Notepad++ to inspect the raw contents of the shortcut safely.
Inspecting files with viewer.online
You can use viewer.online/xnk to analyze .XNK files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Best practices and troubleshooting
Never click an .XNK file from an unknown sender. Shortcuts can trigger unwanted commands on your computer. If your software blocks the file, do not modify your system registry to bypass the security block. Instead, inspect the text content to find the destination path manually.
Software and tools
The main software for this format is Microsoft Outlook. System administrators also manage these shortcuts through Microsoft Exchange Server. For safe inspection, IT professionals use text editors or command-line tools to read the binary or text data inside the shortcut.
Summary
viewer.online/xnk is useful for identifying, inspecting, and understanding .XNK files without installing software or dealing with compatibility problems. If you have an old .XNK file that Outlook refuses to open, our tool helps you extract the necessary folder path safely.
