Download nexus mod manager fallout 4
When you close the Mod Manager or Start the game via the Mod Manager it sets the plugings.txt and DLCList.txt as readonly. I'm not 100% sure but I believe the Fallout 4 Launcher resets them and inserts all esp files in the data folder. The Mod Manager will create a folder " Mods " in Fallout4/Data to manage the installed and activated mods. When logged in, you can choose up to 12 games that will be displayed as favourites in this menu.
