This might sound a bit odd. I have had a Bitcoin app for a few years now. A few years ago I made a copy of Wallet.dat and put it on a stick. Now my computer crashed and i don't know how to import it or where to put it. I got Bitcoin Core and let it install and download the blockchain completely. I was thinking that after the process finishes I will see a folder with a Wallet.dat in it and replace it with my own. However,it has no wallet.dat in it and i don't know how to import my own. What should I do? Did I get a wrong version?
