Try using Resources.LoadAll

Put your prefabs in Assets/Resources/Prefabs/.

This will find all the game objects in your Prefabs folder, and print the amount of them in the console.

 #pragma strict
 
 var prefabs : Object[];
 
 function Start()
 {
     prefabs = Resources.LoadAll("Prefabs", GameObject);
     print(prefabs.Length);
 }

Yes, it can be done.

First, use AssetDatabase.LoadAllAssetsAtPath() to load all assets in a folder:

http://docs.unity3d.com/Documentation/ScriptReference/AssetDatabase.LoadAllAssetsAtPath.html

Then, for each asset, call PrefabUtility.GetPrefabType():

http://docs.unity3d.com/Documentation/ScriptReference/PrefabUtility.GetPrefabType.html

If the return value is not PrefabType.None, then it's a prefab, so you can add it to an array.

Look through the PrefabType return values in the link above. You may want to include/exclude other return values based on your needs.

You could discover all assets in a given folder using AssetDatabase.GetAllAssetPaths () and filter the returned path list.

i.e.:

 string[] assetsPaths = AssetDatabase.GetAllAssetPaths ();
         
 foreach (string assetPath in assetsPaths) {
     if (assetPath.Contains (yourPrefabsFolderPath)) {
        prefabsPaths.Add(assetPath);
     }   
 }

For each filtered path you could load the prefab with Resources.LoadAssetAtPath() and store it in an array.
