It wont recognize .erp files as files. but as simple folders !

Hi, I know the same type of issue has been reported for F1 2016, and now I have this problem for F1 2018.
I tried to understand how to solve the problem by reading the README file of the 2016 skinpack, but I didn't understand very well and it didn't work.
here is what I want to use : https://www.racedepartment.com/downloads/williams-martini-racing-full-team-package.22889/
It would be very gently if you could exactlly explain to me how can I solve this problem and finally install this on my F1 2018 game.
Thank you VERY MUCH in advance :)

The files in there are actually folders. The author wants you to open your actual erp file in your F1 game folder, select the proper texture file in the app you want to replace, and import the texture files from his mod's erp folders. Finally, save and overwrite the original erp file in your game folder.

thanks, so, do I put the erp folders in the main F1 2018 folder ?
