How do I find out which wallet fits which client? I found a really old Bitcoin wallet, a wallet.dat file, and tried to open it. Bitcoin Core told me that the wallet is corrupted. But I also found out that different clients make different wallets, so they aren't supposed to be compatible with each other. How do I find out which client I need to use to be able to open this wallet?
Bitcoin Core is the only software that uses a file called wallet.dat, as far as I know.
