I want to add folders to the Files folder in my project for keeping things organized. For instance I'd like to have an Images folder. Would the call to this folder be DirInternal/Images? DirInternal.Images?
Yes but I think he just wants to organize his project image files.
So he can create a new folder by right clicking in the Files Manager Tab and choosing "Add Group", name it MyImages, for example, drag & drop his files there and then access the files by code just using File.DirAssets.
