About folders and files

Where i must put the "export_desc_unit" file?
What´s the correct folder?
Because i have the original game and only can mod the files into the "campaign" folder (for instance, the mercenaries).

Thanks a lot.:beam:

You need to use the mod switch in order to use modded files.

Thanks a lot

I worked with the mod switch but i have a trouble, What´s the correct folder tree? because in the original installation neither data folder nor base folder are present.
I download the Epistollary´s Richard files, but i don´t know how i must put it.

Thanks and sorry for the question
