Block's undo data is stored in blocks/rev?Huh?.dat.

In C++ source code there are class CTxUndo/CBlockUndo... to do these stuff.

So what does undo data used to do? How it works?

Bitcoin Core developer [PGP] Warning: For most, coin loss is a larger risk than coin theft. A disk can die any time. Regularly back up your wallet through File → Backup Wallet to an external storage or the (encrypted!) cloud. Use a separate offline wallet for storing larger amounts.
