## Multi-wallet environment
Wallets are Berkeley DB (BDB) databases:
Wallets are Berkeley DB (BDB) or SQLite databases.
Subdirectory | File(s) | Description
-------------|-------------------|------------
`database/` | BDB logging files | Part of BDB environment; created at start and deleted on shutdown; a user *must keep it as safe* as personal wallet `wallet.dat`
`./` | `db.log` | BDB error file
`./` | `wallet.dat` | Personal wallet with keys and transactions. May be either a Berkeley DB or SQLite database file.
`./` | `.walletlock` | Wallet lock file
`./` | `wallet.dat-journal` | SQLite Rollback Journal file for `wallet.dat`. Usually created at start and deleted on shutdown. A user *must keep it as safe* as the `wallet.dat` file.
1. Each user-defined wallet named "wallet_name" resides in `wallets/wallet_name/` subdirectory.
1. Each user-defined wallet named "wallet_name" resides in the `wallets/wallet_name/` subdirectory.
2. The default (unnamed) wallet resides in `wallets/` subdirectory; if the latter does not exist, the wallet resides in the data directory.
3. A wallet database path can be specified by `-wallet` option.
3. A wallet database path can be specified with the `-wallet` option.
4. `wallet.dat` files must not be shared across different node instances, as that can result in key-reuse and double-spends due the lack of synchronization between instances.
5. Any copy or backup of the wallet should be done through a `backupwallet` call in order to update and lock the wallet, preventing any file corruption caused by updates during the copy.
