How we can know that asset is real?

How we can know that asset is real exists? Not an instance or copy in memory. Thnks.

Hi, are you looking for this: Unity - Scripting API: EditorUtility.IsPersistent

During runtime, your game exists in memory, but “assets” may have been loaded from the hard disk, downloaded over a nnetwork, or created programmatically within the game itself - there is no way (nor reason) to know which. Is that what you meant?
