Recover Raven coin wallet

Hi all
I used to mine RVN years ago using the Raven—qt miner. Over the last few years, I had some pressing health issues, and I kind of forgot about the wallet.

i wanna try to recover my wallet.. I have an RVN DAT file which is called RVN BACKUP 05.18.dat how do I go about recovering my wallet ? Is this the even correct wallet file? if anyone can help me id be really appreciative..

Cheers..
