However, now I've discovered that it's been occasionally failing, leaving me with some sort of encoded book about once in every dozen. So as I find the failed books I have manually replaced those via ADE.
So, first, is there a known issue with Obok failing?
And, second, is there a way to find these files that failed import without having to view every book? I have several thousand books, so searches take some time, and i haven't found a reliable search yet (Quality Check - Check DRM doesn't find them, so i assume Obok did something to them).
Thank you.

Did you insert the serial number of your Kobo device into the OBOK customization if you are copying the books from your Kobo device? When I look at my Kobo device or the Kobo App library, about 20% of the books show as having DRM, the other 80% are not DRMmed. For whatever reason, Kobo does not encrypt the ePub3 navigation document, the ePub2 NCX document or the CSS stylesheet(s).
As far as I am aware Quality Check does not detect Kobo's DRM scheme so it's DRM check is not going to work however since the cover is encrypted, you should be able to use Quality Check's Missing covers to detect them.
At one point, I was playing with a utility to check if there was a rights.xml file in the root of the ePub's .zip container but never finished it.
