If people didn't have the worst taste ever by playing TDM Nuketown/Hijacked/Raid 24/7, trickshot and cheat zombies with infinite money etc maybe actual decent server owners would have a chance to be popular which would lead to most popular servers not being run by dumbasses like that
Since it won't change gotta accept the community being shit, especially on BO2 and either take the bans or play better servers or host your own

If any folder is missing create it
waleed977 restart your PC and try again
The solution to this error is downloading DirectX and installing it by running the setup to the end
This is pretty much BO7 (whether we like it or not)
Install DirectX
https://www.microsoft.com/en-us/download/details.aspx?id=35
Copy paste a public BO2 script and solve the errors it throws out I'd say in your situation
It's not hard but it depends on your will to learn and ease of understanding, some people struggle for years to open a folder and paste a file so can't tell you how it's gonna be for you, I can only tell you it is objectively, as far as scripting goes, not hard at all (depending on how you do it)

The server docs are not the best since it was written on free time + it assumes people running servers have a bit of knowledge, this is why it might be misleading but I've never heard of what you've said before, although you make sense! 
I recommend using HFS if you're looking for a noob friendly option, it's simple to setup and handles MIME types automatically for you
HFS is a very easy to use web server you can use (for example)
The doc should tell you what you need to know
https://plutonium.pw/docs/server/t4/fastdl/
MIME types are automatically handled by HFS, you don't have to do anything regarding that
Getting Playstation controllers to work on Plutonium is the same as getting one to work with any other PC game that doesn't have built-in Playstation controller support. This is not specific to Plutonium
Easiest solution is to add Plutonium as a non Steam game
Another solution (that will also prevent this issue from happening with any other game that doesn't have Playstation controller no matter the platform, without having to add the game to Steam) is to use a software that does this on the entire system such as DS4Windows, instructions in our doc
It never says FastDL is made to speed up. It says FastDL is how you make the downloading happen
The best way to fix an error is to read what it says and apply a related solution
This is the best I can tell you with the information you provided
What you say is kinda unclear so I'll try to give some answers that may help hopefully
To my knowledge
You might need .iwd to ship textures and stuff in a mod
Thanks for the AI sum up, now I don't have to ask an AI
Select the correct folder
I'm not a dev but some of them have seen what you said and I wanted to say thank you from the Plutonium team 
We're happy that you're having a great time
Hope you'll have a blast!
Add plutonium.exe as a non Steam game and boot it from Steam
In order: don't use bluetooth, have vsync off and try fullscreen or windowed fullscreen if one is better too
