Hello, I'm wanting to install a few mods, but had a couple questions. 1) How do I back up files such as the data folder? Do I just copy the folder and paste in a separate location, or should I email myself the folder and keep it there if I need it? 2) I know one of the mods I want to install replaces the data folder. Do all of the mods replace that folder? If so, how will I be able to have more than one mod at a time running? 3) Will having three mods cause major issues? Is it advised to only have two mods at a time?
