Clever, if this is what it's doing. I had assumed that ebook-viewer as a standalone app would need a book file that had already been decrypted. So it does leave me wondering if my hundreds of previously-downloaded books that I purchased are actually de-DRM'ed, or if they are simply decrypted on the fly when I run ebook-viewer.
Hope this makes sense? I'd like to verify that my hard drive is full of decrypted books that I can open on any of my own devices, rather than needing Calibre installed with the plugin and the Kindle key. I don't tend to keep hundreds of books in the Library, I organize them in file system folders. Is there any way, preferably on CLI, preferably Calibre-native, that I can explicitly list the DRM status of a large number of ebook files? I've not so far had a problem on other devices, but it would be annoying to find out later that I had a number of files that were not actually decrypted, if for some reason I had messed up with my local setup at any time.

Looks like the first part of my question has been confirmed.
Is there any easy way to check the DRM status of a bunch of files?
