Script in Scripts folder can't find namespace of file in Plugin folder

I have this annoying problem where a script in my scripts folder can’t find a file which is located in my Plugin folder. This should work since Plugins folder gets compiled before the scripts folder, or am I mistaken? Error is : "The type or namespace name “SpriteText” could not be found(are you missing a using directive or an essembly reference?).

Both files are c#

from what I have read here it seems your logic is correct. But I have found that calling

using Path.To.Class.In.Prefab.Folder;

does what you need
