- Some wallets use multiple files or a database structure
- Location varies by operating system and wallet software
Common Wallet File Types
- wallet.dat (Bitcoin Core and many derivatives)
- wallet.db (Ethereum wallets like Mist)
- .json (Some modern wallets)
- .key (Private key files)
- Custom formats for specific wallets
Understanding these file types helps our bitcoin recovery service locate and recover your wallet files more effectively.
