It cannot be opened.
We are nearly sure that file was created by Windows for swapping (virtual memory). That file is not used in Linux.
If you are done with using Windows on that computer, you can just delete that file.
If you are still dual booting Windows/Linux, you might still want to delete that file. If Windows needs that file, Windows will recreate it. The contents (while Windows is not running) don't mean anything. Recreating it in Windows is fast and automatic (if needed) and just as good as still having it left over from previous use.
