Creating directory from script

I am trying to create a directory from script while in Edit mode. The problem is directory doesn't get created immediately after the function was called. Sometimes it shows in the Project view a whole minute after. But I need that as a resource directory for MyTool asset.

Why is this happening? Is there some refresh function, or similar that I need to invoke?

Here is a code for details

Code (CSharp):

1. public class MyToolMenu : MonoBehaviour {
2.     [MenuItem ("GameObject/Util/Create MyTool")]  
3.     static void CreateMyTool()
4.     {
5.         createNewTool();  
6.     }
7.  
8.     static void createNewTool()
9.     {
10.         // set resource images
11.         try
12.         {
13.             Directory.CreateDirectory ("Assets/Editor Default Resources/Images");
14.             File.Copy ("Assets/MyTool/Images/background.jpg", "Assets/Editor Default Resources/Images/background.jpg");
15.         }
16.         catch(IOException e)
17.         {}
18.  
19.         // create tool and add it to scene
20.         GameObject tool = new GameObject("MyTool ");
21.         tool.transform.position = new Vector3(0, 1, 0);
22.         tool.AddComponent(typeof(MyTool));
23.     }
24. }

 

Use AssetDatabase.Refresh().
