Have a 12 GB Bitcoin folder back from 2015.. Help?

Hey guys, back in 2015 I vaguely remember using my PC to generate Bitcoins. I have discovered a 12 gb Bitcoin folder on my PC. Containing following folders:"Blocks""Chainstate""6 Datas" - "debug.log" "peers.dat" "wallet.dat" "fee_estimates.dat" "lock" "db.log"​How do I proceed from here? What is this? via /r/Bitcoin https://bit.ly/3Rmrm4E
