My Orbx folder is inside the Addons Storage folder so that I can select what I want from Addons Linker, which will then put it in the Community Folder.
You just need to tell the Orbx Downloader where to put your Orbx addons. How you organise it thereafter is up to you. Example, assuming you’ve told Orbx Central to download to C:/Addons Linker Store/Orbx Library/
Create new subfolders as below then simply move the addons to the relevant subfolder
C:/Addons Linker Store/Orbx Library/UK/ for your UK addons
C:/Addons Linker Store/Orbx Library/North America/ for your USA addons
etc. etc.etc.
Just remember that the file system in Addons Linker is exactly the same as Windows Explorer and the latest version has no limits as to how many sub folder levels you want. When you select your addon it, not the folder, is placed in the Community Folder as a Symbolic Link.
