Use a tool like WinRAR or 7-Zip to unpack the files in the game folder. This'll let you see what's inside those .zip and .ogg files.
Honestly, unless you're modding or curious, you don't really need to open these files. Just play the game and enjoy the magic!
From experience, I recommend not messing too much with the files unless you know what you're doing. Corrupting them can be a headache!
