I don`t have that folder. The only place where cannabis exist is C:/program files/cannabiscoin. And there is three files there:
cannabiscoin-qt(app file) ; copying(txt file) ; uninstall.
Should i put this "dat" file in this folder?
some of the folders appdata & roaming could be hidden. if you have opened the client then you should have these folders: C:\Users\xxx\AppData\Roaming\CannabisCoin
