I have looked under C:\Users\username\AppData\Roaming where other QT wallets have saved dats but there is no trezarcoin folder.
It is also not in the same folder as the QT application either.
Is there a way to query the QT wallet to tell me the location?
Look in the folder where the trezarcoin-qt.exe is located and there will be a subfolder labeled data. Wallet.dat is in that folder.
Your wallet.dat is in the /Trezarcoin/Data Folder.
There is no discord.
Is your wallet fully synced? You will only see the coins in your local wallet when your blockchain is up to that date where you have sent these coins.
