File Types and Storage

1. Multibit Classic:
   • Uses file extensions .key or .wallet.
   • Files can store multiple keys.
2. Multibit HD:
   • Employs file extensions such as .aes.json or .zip.aes for backup.
   • Designed for encrypted backups.

Key Storage Mechanism

1. Multibit Classic:
   • Each wallet contains a .key file.
   • The .key file stores a single public key.
2. Multibit HD:

   • All addresses are derived solely from the 15 words, eliminating the need for individual .key files.
