Help! I cant open my backup .dat file

Hello everyone
how do I open a .dat file. I saved my Litecoin Core wallet but I cant read it.
Help me!
Thanks.

Have you had good luck with this?
Wich operative system are you using?

It’s just another Litecoin scam. Litecoin has all kinds of way to steal your money. Charles Lee must have learned this from the master “Coinbase”.
