- In this wallet, you can set a password for sending funds.
- All funds in the form of bitcoins are stored in one single file called wallet.dat
- After setting the password, the file is encrypted, and you can use the tools only by guessing the correct password.
- We sell this wallet.dat file with lost or forgotten password.
Wallet.dat is the key to your own virtual wallet in the entire Bitcoin Network. A loss of this wallet file means the safe and irrevocable loss of the money supply located there.
- First, close the Bitcoin-Qt client.
- Then you have to locate your Bitcoin folder. For Windows, it should be here: C:\%Users%\%Username%\AppData\Roaming\Bitcoin\wallets, For OS X ~/Library/Application Support/Bitcoin/
- In that folder, there should be a wallet.dat file.
- If you currently have no bitcoins in your wallet, you can just delete that file and replace it with your backup.
- If you have some bitcoins in this wallet as well, backup that wallet file as well, or send all the coins to an address from your backed up wallet.
- When you placed the other wallet.dat file in place, you should run Bitcoin-Qt with the -rescan option. Here’s how to do that in Windows:
- Go to C:\Program Files (x86)\Bitcoin using Windows Explorer.
- In that folder, hold shift and right-click and select Open command window here
- In the command prompt, type bitcoin-qt.exe -rescan and hit enter
- Now Bitcoin-Qt should start and rescan the blockchain to calculate the balances of the addresses in your wallet.dat file.
