It was not really about that; but rather about the huge amount of wallets without passwords that are being sold these days (that can't be unlocked in a human lifespan). Most recent case being this one. If you say the wallet is really yours, there is no reason to not believe you; and the only thing I wanted to make sure was that it was really the case.

Now going back to your case...

Do you know if all the wallet files are from bitcoin; or could they be mixed with other altcoins? If you are not sure about it; you can follow one of these 4 procedures:

There are 2 3 ways :
1. Download client for cryptocurrency you think you own/use in past and load wallet.dat into that wallet client/application
2. Open your wallet.dat with any text editor and look for text/string which represent a cryptocurrency (on Bitcoin Core, usually list of the address are on bottom of file/line). It's painfully slow method and i don't recommend this method.
For example, on my Bitcoin testnet wallet, there are 14.6K lines and i found list of my address on line 14357
3. Use pywallet (https://github.com/jackjack-jj/pywallet) to get list of address of your wallet.dat. Check https://bitcoin.stackexchange.com/a/25315 for more information

Make sure you backup your wallet.dat before doing anything else.

Actually just search for "name" and the address will be right next to it.

It's from another thread from some months ago with a similar case; old wallet files

If you don't know in which address the coins are, you can dump the whole wallet with --dumpwallet. That will create a file that you can open with a text editor, and will contain the private masterkey and every private key with its correcponding address. You can manually check them, or simply sweep all/the masterkey
