Seaching hard drives for non-Bitcoin wallets?

[Paycheck]

I'm familiar with Bitcoin Core wallets, and their wallet.dat files.  I've looked at old computers and searched them for wallets. 

But what about non-BTC wallets?  What is their version of the wallet.dat file and what to search for to find them?  How about other types of BTC wallets?

Does Litecoin Core have the same wallet.dat?

Anyone know about this?

Any different wallet used the different extension too. But i never heard if bitcoin core was having a feature to be used to store our altcoins, is this kind of a plugin only?
If that was created or build in the same wallet and it must have the same extension too.

I stopped using or storing bitcoin core type of wallets but from my past, they are only known as wallet.dat or a seed or mnemonic phrase just like what I've had with blockpool but you can get help if you can a screenshot of your wallet folder so experts can trace them here.
