Save/ Load in Editor created meshes

Hi all,

first sorry for my bad english :)

i have a problem with save and load per editor script created meshes.. I create a Terrain in Editor from heightmap and save them to my assets as .asset, afterwards i split this terrain in many small meshes with only 2 triangles and save them,too! Here the code how i save a mesh:

  Mesh newMesh = new Mesh();
  newMesh.vertices = Vertices;
  newMesh.uv = UV;
  newMesh.normals = Normals;
  newMesh.triangles = Triangles;
  newMesh.RecalculateNormals();
  newMesh.RecalculateBounds();
 
 filePath = EditorUtility.SaveFilePanelInProject(
 "Save Mesh in Assets",
  newTerrainName + "_Mesh"+".asset", 
 "asset","Please enter a file name to save the Mesh to ");    
                       
 if(filePath!="")
  {
     AssetDatabase.CreateAsset(newMesh,filePath);
     AssetDatabase.SaveAssets();
  }

to save is no problem and i see the new Mesh in my Assets with the mesh Icon... when i drag and drop this mesh in a meshfilter it works fine...

know to my real problem, because i have a lot meshes( 1000 or more ) which i want to save in a array in editor, i want to take all meshes from a folder to save them in this array.. but i dont't know how:

here my code so far:

     string currentFolderPath = Application.dataPath + "/"+folderPath;
 if(System.IO.Directory.Exists(currentFolderPath))
 {
     Debug.Log("Directory Exists");
                     
     Mesh[] allMeshes;
     string[] allObjectNames = System.IO.Directory.GetFiles(currentFolderPath);
     allMeshes = new Mesh[allObjectNames.Length];                
                 
     for(int j = 0; j < allObjectNames.Length;j++)
     {

                     //what i have tried
         //Mesh obj = (Mesh)(AssetDatabase.LoadMainAssetAtPath(allObjectNames[j])as Mesh);
         //Mesh obj = (Mesh)AssetDatabase.LoadAssetAtPath(allObjectNames[j],typeof(Mesh) 
         //allMeshes[j] = obj;            
                 
     }
  }

thanks for help..
