Script for locating missing files?

I'm using this script:

 using UnityEngine;
 using UnityEditor;
 
 public class FindMissingScripts : EditorWindow {
 
     [MenuItem("Window/FindMissingScripts")]
     public static void ShowWindow()
     {
         EditorWindow.GetWindow(typeof(FindMissingScripts));
     }
 
     public void OnGUI()
     {
         if (GUILayout.Button("Find Missing Scripts in selected prefabs"))
         {
             FindInSelected();
         }
     }
     private static void FindInSelected()
     {
         GameObject[] go = Selection.gameObjects;
         int go_count = 0, components_count = 0, missing_count = 0;
         foreach (GameObject g in go)
         {
             go_count++;
             Component[] components = g.GetComponents<Component>();
             for (int i = 0; i < components.Length; i++)
             {
                 components_count++;
                 if (components[i] == null)
                 {
                     missing_count++;
                     Debug.Log(g.name + " has an empty script attached in position: " + i);
                 }
             }
         }
 
         Debug.Log(string.Format("Searched {0} GameObjects, {1} components, found {2} missing", go_count, components_count, missing_count));
     }
 }

I hope this is what you are looking for. I won't take the credit, since I found it some time ago, but I can't remember where
