At the process level I can't see any difference in Task Manager between viewing an epub via the calibre library manager, and viewing an epub that has never been anywhere near calibre until I opened it from File Manager.

The one boxed in green (AI and Digital Leadership) was opened from my file manager, the one boxed in red (The Bankers New Clothes) was opened from the calibre library manager.
