The .wallet file cannot just disappear. It can be deleted, like any file, or, which is more probable, the recently opened wallets history was deleted, which is not in any way critical. We will look into that, to make sure this doesn't happen, because we haven't experienced it until now.
The default save location is in the same folder the app was installed in, but this location can be changed by the user.
A search for .wallet files is the first thing to do. After locating it, either keep it there, ore move it to a chosen location which you will remember. From the CroatCore app, use the Open Wallet button and browse to the wallet's location.
If you don't find the .wallet file, then you can recover it by using the private keys and importing them into the app. In the CroatCore instructions it is recommended to export the wallet's keys and keep them in a safe place.
We cannot stress enough how important it is to treat you wallet like you'd treat cash. Make sure you know where you save it, like you'd know where you keep you physical wallet. Be careful when writing the password. Don't forget it. Export the keys right after creating the wallet and keep them in a safe place. Make as many backup copies you see fit of the wallet, the password, the keys, and keep them safe, just like physical cash.
There is no other possibility to recover a wallet and there is nothing that the developers can do, even if you send us your wallet address.
thanks for the support, I returned the purse, with it everything is fine.
But there are some problems:
I have 6 farms, 4 is excellent, and 2, after restarting Windows 10 64bit there are no wallets, as I have just installed the application, and each time I need to specify the path to the wallet in the program folder, specify the address of the pool.
so on 2 of the 6 farms.
This is a comment to the programmers to correct this bug for the future.
For me, he is not critical.
and yet, after opening a purse, I can not immediately start mining, sometimes it takes 5 minutes to wait, a "Daemon ..." notification appears and you just have to wait.
I think to reinstall the application.
I have all the same farms, the components are identical, windows and other programs and settings too, all farms work in 1 network.
