Howto Backup ZCash4Win Wallet ver 1.0.12?

Hello, I just installed ZCash4Win wallet for the first time, but after selecting a transparent or private address, and selecting a backup folder, the GUI briefly works, but does not create any file at the location selected.

Question: Can I just save the Wallet.dat and my private keys, is that enough for restoring the GUI later on?

What is the purpose of private addresses? I guess transparent is my public address…

Thanks for your help!

Thats all i ever did. If you have access to a 2nd device you can install on that and select import private keys from your backup, it should effectively create the same wallet SO YOU CAN BE SURE your backup is good. Just uninstall and delete the app roaming data ( window search %appdata% ) if you dont want the other wallet.
