Did you find an XNK file on your computer and wonder what program should open it? Maybe someone emailed you an XNK file but you're not sure how to use it. Perhaps you tried to open the XNK file but Windows told you that it could not open it.
Before you can open an XNK file (assuming it's even a file format that's intended to be viewed or edited), you'll need to determine what kind of file the .XNK file extension refers to.
Other types of files may also use the XNK file extension. If you know of any additional file formats that use the .XNK extension, please let me know so I can update this information.
How To Open an XNK File:
Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with. See my List of Executable File Extensions for a listing of file extensions to avoid and why.
XNK files care shortcuts to folders or other items in Microsoft Outlook so double-clicking on one will do just that, assuming you have Microsoft Outlook installed.
Important: Microsoft removed XNK support beginning in Microsoft Outlook 2007. If you have that version of Outlook, or later, you'll have to make manual changes to enable this feature. See Microsoft's instructions here and here for more on this.
If Microsoft's solutions didn't work, you can try two registry modifications using this guide at MSOutlook.info.
If you know anything else useful about XNK files, please let me know so I can update this page.
Tip: Use Notepad or another text editor to open the XNK file. Many files are text-only files meaning no matter the file extension, a text editor may be able to properly display the file's contents. This may or may not be the case with XNK files but it's worth a try.
If you find that an application on your PC does try to open the XNK file but it's the wrong application or if you would rather have another installed program open XNK files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.
How To Convert an XNK File:
There are two main ways to attempt to convert an XNK file to another file type:
- Open the XNK file in its default program and choose to save the open file as another file format.
- Use a File Conversion Online Service or Software Program to convert the XNK file to another file format.
The first option involving opening the XNK file in its native program is preferable because it's both easier and will probably result in a more accurate file conversion. Of course if you don't have a program that opens XNK files, a third-party file conversion tool (the second option) could be very useful.
Important: You cannot usually change a file extension (like the XNK file extension) to one that your computer recognizes and expect the newly renamed file to be usable. An actual file format conversion using one of the methods described above must take place in most cases.
