Please note, this is a wallet.dat file that is about 6 months old and I haven't loaded it in at least four months. I'm not sure if that makes a difference or not...
Now I would like to import my original wallet.dat from the old client which was encrypted into an new version of Bitcoin-Qt.
So wallet file will be built into the core and accessible via API calls. This wallet file will be password protected itself, with an easier to remember password.
This took too long to complete so I decided to capture my wallet.dat file and to abort the installation of the blockchain. Now I want to download a lightweight wallet to start with.
This specific wallet.dat file stores transaction data and all other related information (keys, metadata, options) about your Bitcoin activity.
But other DAT files may not be text files - it depends entirely on what the DAT file is being used for.
Import Wallet Create a new wallet by importing an existing wallet file. Drag the wallet file into the area above. Supports Bitcoin-Qt (wallet.dat) and blockchain.info (wallet.aes.json) files.
I recently imported the encrypted wallet.dat file into the bitcoin-qt wallet on Windows 7. Coins appeared. But, my expected passphrase is incorrect.
Encrypting your wallet.dat file is the number one thing you should do followed immediately by making a dual paper copy of your password/passphrase and storing it somewhere safe.
You can backup your wallet.dat file, complete several transactions and keep using the new addresses to receive money with no problems.
