V5 file saves to desk top are not consistent, some times icons have thumbnail sometimes not?

With win 10 . Some times I save my rhino 5 files to my desktop they have icon with a thumbnail of the saved drawing, and sometimes I save files to my desktop and just get the black and white rhino icon with no thumbnail. What determines which condition will occur?. In my folders all files just have the picture of the rhino, and Im ok with that, I just would like to know whats causing the inconsistency with the saves on the desk top, and just have it all consistent. I would prefer no thumbnails there to small to really see what they are any way.

Thanks

Hi Lisa,

If Explorer is not showing file extensions, then the black and white Rhino icons you’re seeing might be backup (.3dmbak) files.
