If you use Fomm ? it's all automatic, no need to worry about there it puts things. It was designed specifically for this game.
It will "however" eat a lot of drive space. it's not game breaking. Just the nature of that beast.
you follow the instruction last written on the other users thread, as he followed them until you leave vault 101.
you hard save at that point and wait untill all DLC's lof in. hard save again and exit.
From that point on, you need to think hard about the load order of the different mods, where they ending up.
That's why it best advised to start out small. Not Drop bombs into the games engine.
The conflicting mods...so many you had listed...you need to sift through them. decide what to keep and what not to keep.
Code, there are "Code bases", plain normally made mods from games assets are considered normal mods.
Script extender mods are not of the same CODE base, they are 3rd party mods.
ENB's are not even mods ! they are Direct-x and graphics changes to the OS For the game.
so you need to sort out wat you want and what works with what.
I'm here just to get the game up and running. Not make decisions for you.
