Inventor 2019.3 - Access Files Thumbnail Inside Inventor

I am aware that the recently used list for Inventor is kept in the registry

HKEY_CURRENT_USER\Software\Autodesk\Inventor\RegistryVersion23.0\Recent File List


This list is used by the Home screen to show all recent files. Where does the thumbnail come from that the home screen displays

What mechanism does the home screen use to display the thumbnal without opening the file first. I can already view the thumbnail within Inventor (NOT apprentice) , but I have to open each file to read its iProps

 

 

Cheers

It seems that when Inventor opens, a bunch of JPG's are created in the Temp folder ( %Temp% ) in a similar format too 262B.jpg, 262C.jpg, 262D.jpg. These are the thumbnails used on the home screen. They are removed when Inventor closes, therefore recreated from scratch (with different names) every time. Is there somewhere in the Registry I can query, and anything anywhere I can query to get the correct JPG associated to each entry in the Recent File List
It is quite computationally expensive to open a file just to read an iProperty, then close it again. Especially if there are many files in the Recent file List, and double especially (?) if they are big files.
