Re: [ANN] Zettelkasten - ZETTEL, coin with new hashalgo - CPU-mineable (for a while)
hi dev how to backup the wallet? 
You will find the "wallet.dat" file in C:\Users\%username%\AppData\Roaming\ZettelKasten. All you need do is copy this file and save is somewhere safe (AFAIK).
Another method is dumpprivkey and save them somewhere safe
