Please let us know how you get on. To me your addons directory looks fine, if somewhat long-winded. I’d shorten those file names, no need to repeat what category the files are.
Been using MSFS Addons Linker since the beginning - with something like 700GB of addons there’s no way I could run the sim without it. To me keeping the addons separate from the Community/Official folders is the whole point. I keep all mine on a separate Nvme drive that I can take with me so I can use them on my laptop if away from base.
