What do the exe files in the tools directory do?

[ffMathy]

For instance, koolo-map.exe and handle64.exe. What do these do? Are the source codes for these programs available too?

[artosimonyan]

koolo-map.exe generates a collision grid/map from the in-game map seed, using the Diablo 1.13c game files, which Koolo then uses to navigate around all areas. Source isn't available. It is based on another open-source tool - https://github.com/blacha/diablo2/tree/master/packages/map

handle64.exe is a Microsoft tool that kills the process' handle allowing us to launch multiple instances of the game.
