Hello or good evening (I speak with google translate, so sorry if there are mistakes in my sentences )

I know that you must use xv2 characreat and select the 3-letter folder containing the emd emb files but I wonder: how to get these famous files? A long time ago I created a 3d model but I couldn’t use it, and I want to try again but I don’t know what to do after the modeling, can you help me please?
Thank you! if you speak french i will understand better
