anyone know why it makes new ones? is it important to let it make new ones. or doesnt it matter
It's not really important, it's just how a patch works. It looks to see what files you have and compares them to what the patch has. If something is different than in the patch, it overwrites the files. It probably overwrites the .ini because if some performance things changed than it might be a good idea to change some settings to take advantage of the new changes.
