Hope somebody can help me,

Back in 2015 I tried to mine eth and litecoins, I comepletely forgot about it until recently when I connected my old HDD back to my PC.
I have found an ETC folder in the roaming profile which is approximately 5 GB along with a Litecoin folder of similar size. Is it possible to see if I successfully mined any old ETC or Litecoins coins?

I have had some luck already where I had an airdrop of Decred and manage to recover the coins using the seed key provided which I managed to keep safe.

Thanks.
