HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Or what are we talking about then?

Here's an example. We played a 2v2 game, with 4 passwords. After the game is played and I enter all 4 passwords and open the map in single-player (or hot-seat), it would be nice if all 4 passwords were saved in one file, so that later I don't have to search through the history in ICQ logs if I need to view the saves after some time.
