Ask about saving data in unity 4.6.6f2

Hi all,
I am using Unity 4.6.6f2 to draw a device in Unity.
I want to check the number of devices drawn in the scene.

How can I check this? I have performed the following steps to find where the data is saved:

  1. Draw items.
  2. Delete all files (*.wdg, *.ncd).
  3. Close Unity.
  4. Open Unity and check if the design image still displays normally.

I want to verify where it is being saved.
Could you please support me with this?

Hi, your question is unrelated to today’s Office Hours event. I’ve adjusted your topic’s tags to be more appropriate.

That version is 10 years old. Legacy project I presume?

What “devices”?

Never heard of these extension. What are these?

Where is what saved? You didn’t mention any steps that “save” any files.
