Had someone in the dogecoin discord come in with a similar problem, and we found that .wallet
files are used specifically by WowDoge, as far as we can tell. WowDoge, as far as we can tell, is a deprecated dogecoin wallet that is no longer able to talk to the network. But it can use the .wallet
file, and you can use it to get your private key, which you can then import to something like Dogecoin Core to talk to the network and transfer your coins.
I encourage you not to trust random links on the internet, but I'll give them to you anyway.
WowDoge's github, which is not particularly useful: pavel4n/WowDoge
The WowDoge website that is currently up, and for some reason not the .org domain provided on the github. This is where you will find Windows/Mac downloads. https://www.wowdoge.app/
Drop by the dogecoin discord if you want more help with that, and please please please be vigilant, there are many many scammers who would absolutely love to get a hold of your coins and pretend to help. never ever give your wallet files to anyone, never share your private key, never "connect your wallet" to anything. Stay safe, and good luck!
