Launcher add dlc to a project issue

please make sure that the launcher where you can add dlc to a project not contains config or project files.
or if the launcher say “dlc files already exist in this project” make a list popup where you can deselect files. (unity as shining example)

if you add a dlc that you never added to a project pop up a message files exist, people (like me)
will continue this dialog and in worse case config files are overwritten.
