path	Pathname of the target folder.
systemTypeInstance	Type filter for objects returned.

Loads all assets in a folder or file at path in a Resources folder.

If path refers to a folder, all assets in the folder will be returned. If path refers to a file, only that asset will be returned. The path is relative to any Resources folder inside the Assets folder of your project.

Note:
All asset names & paths in Unity use forward slashes, paths using backslashes will not work.

	// Loads all assets in the "Resources/Textures" folder
	// Then picks a random one from the list.
	// Note: Random.Range in this case returns [low,high)
	// range, i.e. the high value is not inclusive.

		var textures : Object[] = Resources.LoadAll("Textures");

path	Pathname of the target folder.

Loads all assets in a folder or file at path in a Resources folder.

If path refers to a folder, all assets in the folder will be returned. If path refers to a file, only that asset will be returned. Only objects of type T will be returned. The path is relative to any Resources folder inside the Assets folder of your project.
