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?

it's used when there is a block chain reorganization

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 FileBackup Wallet to an external storage or the (encrypted!) cloud. Use a separate offline wallet for storing larger amounts.
