Re: question about modding
they mean copying the file but remaming the copy such as, for this explanations sake, "EB EDU" and when you backed it up, you wuold call it s/t like "copy of EDU" or s/t. the point is if a minimod goes bad, you still have the original text to repair the damage.
Re: question about modding
BTW, it so much quicker to install eb if you do it manualy, using 7zip or s/t
Re: question about modding
It means just save your original file to other location in case your modded files get messed up
