Hi, I found a program that teaches you what is inside the folder of Diablo III, is called Cain's Aide.
This program does an impressive job. Find files older than it was Diablo III, before the Blizzard North team will stop working at Blizzard. And models, achievements, weapons, characters, maps, PVP, settings, etc, etc than Diablo III currently has among other things really impressive.
installation:
*Download Cain's Aide
*Unzip the. Rar wherever you want.
*Open the program ''CainsAide.exe''
*Find the folder of Diablo III
Enjoy!
if you learn to handle it, you will see future content patches and even icons of games like: World of Warcraft MoP CE.
Just get the patch 1.0.4, it would be advisable to check with the program content.
sorry for my bad English hehe.
