Cannot find 3D Prefab after doing a build.

Steps to Duplicate Issue: 1. I have an FBX object that I broke up into 30 FBX objects.
2. I created 30 Prefab objects from those 30 FBX objects.
3. I built a script to load all of the prefabs names into the DropDownList.
4. Then a user clicks on a Prefab name in the DropDownList and then I instantiate and load the Prefab.

It works great in the Unity editor because I use UnityEditor calls(AssetDatabase...).

When I do a build I cannot use UnityEditor calls. This line causes my App not to build: prefab = AssetDatabase.LoadAssetAtPath(myPath, typeof(UnityEngine.Object)); The error states to not use UnityEditor inside the app. Which makes sense.

If in my App I put the path to the 30 Prefab objects in my build directory it works fine.
QUESTIONS:
How do I find the Prefab objects after the build? It seems my objects are in a resources.assets file.
Are my Prefabs objects in the resources directory of my build within an assets file?
Can I grab them by name?

Code snippets:
LOADING DropDownList

     FBXPrefabInFolder = new List<string>();
     FBXPrefabFileSize = new List<long>();

     string strdir = new DirectoryInfo(AppLevelPathPath).FullName ;
     DirectoryInfo dir = new DirectoryInfo(strdir);

     FileInfo[] info = dir.GetFiles("*.prefab");
     foreach (FileInfo f in info)
     {
         if ( f.Extension == ".prefab")
         {
             string tempName = f.Name;
             string extension = f.Extension;
             string strippedName = tempName.Replace(extension, "");
             FBXPrefabInFolder.Add(strippedName);
             FBXPrefabFileSize.Add(f.Length);
             drpPartsOnDisk.options.Add(new Dropdown.OptionData() { text = strippedName.ToString() });
         }
     }
  

LOADING PREFAB

private UnityEngine.Object prefab;
public GameObject instance;

GameObject GO;
prefab = Resources.LoadAll< UnityEngine.Object>(AppTHISISSEARCHPath + inpPartText.text);
GO = prefab as GameObject;
instance = Instantiate(GO) as GameObject;
