5. Best Practices for Management
- Regular Backups: Even with HD wallets, it is good practice to back up
wallet.datoccasionally to preserve metadata (labels and contacts). - Seed Phrase Supremacy: The
wallet.datfile is a technical file; the Seed Phrase (12-24 words) is the human-readable backup. Storing the seed phrase securely renders thewallet.datfile replaceable, but not vice versa. - Never Edit:
wallet.datis a binary database file. Opening it in a text editor and saving changes will almost certainly corrupt the file and result in permanent loss of funds. - Descriptors: Modern Bitcoin Core (v22+) is moving toward "Descriptor Wallets." These function slightly differently (storing output script descriptors) and may eventually supersede the legacy
wallet.datstructure, though the filename concept remains.
- GUI method: Open Bitcoin Core. It may prompt, "Your wallet needs to be upgraded. Continue?" Click Yes.
- Command-line method:
