I still don't understand how Bitcoin Core stores blockchain data. I mean I look at my computer and I've got these different folders, but I don't understand how Bitcoin Core builds the database of blocks and transactions. My understanding stops somewhere around there is a UTXO set and that's different than the blockchain dataset.

TLDR: A Google-made database called leveldb stores all the information around blocks but the blocks themselves just lie around in the file system as .dat files

The main changes vs 0.11 off the top of my head are txindex move to async indexer and the utxo change to per-output granularity?
