Litecoin folder on my mac from 2013

Has blocks folder with .dat files and index folder with .sst files. And chainstate folder with .sst files. What is it? Did I buy some in 2013? I don’t recall.

I’d search for a file called wallet.dat and make copies of immediately. I mined hundreds of LTC in 2013-2015. Actually running litecoin-qt may fire up the client and show a balance. I’ve found hundreds of $$$ I left as change on my old machines.

Found wallet.dat from same time. Still no idea how to open or access.
