Hello, wondering if someone knows the answer to these two questions.

When I create a wallet in Armory, there are two related wallet files in the \Armory directory that get created as well
armory_walletID.wallet and
armory_walletID_backup.wallet

What's the different between these two files?

And the wallet.dat file in the \bitcoin director does not contain any information regarding the wallets created via Armory, correct?

Thanks
