Those would be more useful with Skyrim, because I had many problems (crash without error after some minutes of gaming, it didn't depends from the location, the movement, actions, speaks or other similar recurring problems. It crashes after 2-3 minutes, even with new games and game file re-checked by Steam). For now in Fallout I don't need them. NMM is perfect, the only one problem is that after every small update it removes and reinstalls all mods (so I don't have the lastest version, but the previous one). I always run the game with F4SE, even if it's outdated (F4 updated some days ago on Steam, but the F4SE 1.18 doesn't support that version yet). Yesterday deleting all files in that folder, solved the problem. But I didn't know of those files until I found a Reddit discussion of "How reactivate your mods after last updates", that tells to put an asterisk * before all ESP and ESM plugins, because NMM doesn't do that yet. I tried, when I saved the file, it told me that it was "read only". So I deleted all of them, reactivated all mods with NMM (that inserted asterisk on those activated) and finally played with all mods.
