This tool helps you to install mods. Tthis means that chosing the appropriate option, new BH files will not contain references to all files you have edited and stored directly in folders, also when original files is even contained in your BIG archives! From this version, by clicking the right mouse button, you can set any path as new main game folder. This option is useful for those who love to play in several ways, with more than one version installed at the same time, allowing them to rebuild the indexes correctly and independently for each version.
