Add prefabs from a folder to array as GameObject

i guess only this line is enough to put objects in an array:

folderObjects = Resources.LoadAll("NAME OF FOLDER");

until and unless all your prefabs are not in same folder.

if prefabs are in different folders, then just load from the resources and add in array or better keep in list because its dynamic.

Here you go:

 public GameObject[] folderObjects;
 public List<GameObject> testingList;

 void Start () {
     folderObjects = Resources.LoadAll<GameObject>("NAME OF FOLDER");
     //Important note: place your prefabs folder(or levels or whatever) 
     //in a folder called "Resources" like this "Assets/Resources/FOLDERNAME"

     foreach (GameObject i in folderObjects)
     {
         testingList.Add(i);
     }
 }

I've added in a list just so you can see whats in the array

I'm curious as to why you need to put stuff from a folder into a list. Could you tell me? If you don't want to that fine
