Is there a way to convert a .nfv file to watch on PC?

[lebble]

So, I've downloaded a file on my phone from NF (first time ever as I have an account) and now I'm trying to find a way to convert it (a .nfv file) into something that I can watch on my PC.

I've read all forum's threads about recording video from NF and even tried some ways (in the borders of my technological knowledges), but first, I failed with all them, and second, I still believe there must be a way to hack (Oops) the file rightly.

So... well...

I would not stop to search for a way to do it but would be very grateful for your help here
