Creating an array of objects in the order they are in a folder?

Hello,

I have a folder in my resources folder called Levels. Inside this, i store all my levels as prefabs that can be instantiated when needed. I firstly load them into an array using Resources.LoadAll("Levels")

The levels in the folder are named as follows: Level,Level 2,Level 3 etc

In the folder, they are in order so level is first, then level 2 and then level 3. But when i create an array, they are not in order, for some reason. My question is how i can make sure the array is created in the order the prefabs are in the folder.

Any help is greatly appreciated, thanks.
