Notes about the XLNK file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The XLNK file type is primarily associated with 'XML Link File' by Tom Arn. An XML Link File (.XLNK) is an open and platform independent shortcut file that references a file or a directory. It has the same function as the Microsoft Shortcut File (.LNK) but is not limited to the Windows platform. And, unlike the LNK format, the format of the XLNK file is publicly documented.
