Resources.load failed

I'm trying to create a new gameobject at runtime and assign it a mesh.
In my subfolder Assets/toto there is a 3ds file named mymesh.3DS including a mesh named struct (I can chek the mesh named struct in the Mesh selection Editor of Unity).

My instructions are :

Code (CSharp):

1. Mesh TMesh = (Mesh)Resources.Load("Assets/toto/mymesh.3DS", typeof(Mesh));
2.             var Objet = new GameObject();
3.             Objet .AddComponent<MeshFilter>();
4.             Objet .AddComponent<MeshRenderer>();
5.             Objet .GetComponent<MeshFilter>().mesh = TMesh;

But the mesh does'nt load when I run the script. I can check it in the EditBox of the mesh Filter editor indicating None (Mesh)

 

Hello.
You probably have the same problem :
https://forum.unity.com/threads/resource-load-question.505348/#post-3294123

https://docs.unity3d.com/462/Documentation/ScriptReference/Resources.html
"All assets that are in a folder named "Resources" anywhere in the Assets folder can be accessed via the Resources.Load functions. Multiple "Resources" folders may exist and when loading objects each will be examined."
https://docs.unity3d.com/ScriptReference/Resources.Load.html
"The path is relative to any Resources folder inside the Assets folder of your project"

(Resources.Load need a Resource folder to be able to Load a file)

 

oh well I'm an idiot too. Thks a lot!
I cumulated 2 errors, the folder and the extension.
