Your vault settings, plugins, starred, templates, etc. are all stored inside your vault under a hidden .obsidian folder. As long as you copy your entire vault folder, you should be good to go.
It’s not necessary to also copy the files in your app settings folder. Although it does contain information like the list of your vaults. And other stuff like cache information. So if you lost that folder, you would just have to add your vaults to the list again. But your vault(s) would be intact.
From the docs:
on Windows %APPDATA%\Obsidian\
And you can find your APPDATA folder like this:
(If you hit Windows-R and type %AppData% in the run box, it should take you there.)
