After following the steps on this post and watching numerous videos what I'm getting at is I need to replace the "test" wallet.dat file with the backed up wallet I am trying to access. After I do this however, when I click file>open wallet>, I only see "test" and not the other wallet.
That's normal since you've just replaced the wallet.dat inside it.
If there's no 'wallets' folder in the data directory, Bitcoin Core will list the folders' names with wallet.dat file inside them (in your case, the 'test' folder).
This is why I'd suggested to rename the copy of the old wallet.dat and paste it into the 'wallets' folder so Bitcoin Core would recognize both wallets when using the 'load wallet' menu.
Replacing the wallet.dat was good for the old version when the multi-wallet wasn't supported, now Bitcoin Core can handle multiple wallets at the same time.
I would suggest a single "
wallets" folder in the bitcoin data directory where you can paste wallet.dat file(s) (
with different names).
Then Bitcoin-qt will be able to recognize wallets in that folder using 'Open Wallet' menu.
By the way, the
dumpwallet command in my post above can be used even without downloading the blockchain.
You can immediately export the keys and addresses right after loading the wallet.dat.
