I bought my friend's old computer from 2011 or so.
Then I found a Bitcoin folder from the User/Appdata/Roaming area. It had a wallet.dat file in there and I thought I might be able to restore his Bitcoins - in case there are any.
I proceeded to install Bitcoin Core so I could open the wallet. I have downloaded about 5% of the blockchain. But then I realized the fresh install of Core probably overwrote the previous wallet. What do I do? Could it do that?
%APPDATA% roaming...
you need detelete the new wallet.dat and put the old
It will update the format probably but not replace it
Try to use command line to check what are the public addresses and check the balance
This. Could be a waste of time
Well first of all you save everything on a USB key before touching it.
And then you check for solutions on the internet before clicking.
On something that risky you cannot just launch it like that
should have saved a backup of the .dat anywhere while its downloading the chain
Guys are you saying I just possibly overwrote 100 BTC or so
>Try to use command line to check what are the public addresses and check the balance
How do I do this? I'm a noob so I'll need detailed instructions.
Let me pc post brb
1. ShutDown BitCoin Client
2. Find your wallet location (%APPDATA%\Bitcoin) OR for example : C:\Users\UserName\AppData\Roaming\Bitcoin
3. Backup, verify, then delete that wallet.dat file
4. Paste your other wallet.dat file into the folder.
5. Open BitCoin Client , blocks get checked and updated, and you should see your amount.
