I want to restore my bitcoin wallet which backup in 2013, I have the backup folder and a password(not secure words).
Anyone know how to do?
Do you want to loose part of your bitcoins?
In every transaction you do new "wallets" are created and stored within your wallet and part of the bitcoins is moved from the original to those addresses to avoid tracking of addresses from outside observers. Those transactions will be lost forever.
If you haven't done any transaction since you made your backup just restore the wallet (make a backup of the new one just in case) and resync transactions, that should do it.
