calibre, version 7.26.0
count pages version 1.13.6

Probably just missed something in the FAQ. Maybe someone can help.

About 6k books imported to Calibre. Sanity checking the books for corruptions/errors with count pages plugin.

Estimate page counts using Algorithm: "E-book viewer (calibre)".

About 200 books failed to page count with errors (mostly "No convertible format found").

Spot checking some of these books, they all open and paginate fine with the calibre e-book viewer.

One book for example, calibre library says it is format "azw" (not azw3 for whatever reason). It opens fine in the Calibre e-book viewer (viewer title bar says KF8).

I suspect it is because Calibre library is reporting these as format:azw instead of format:azw3 for some reason? Not sure why they imported that way when Calibre e-book viewer reports them as KF8 (same as azw3 right?).

format:KFX also doesn't count pages even though I have the KFX input plugin and they open fine in the calibre e-book viewer.

So it looks like the pattern is the format reported by Calibre library (rather than whether or not the calibre e-book reader can open and paginate the books).

These count pages: azw3, mobi
These don't: azw, azw4, kfx, HTMLZ

All of them open fine in calibre e-book viewer.

I hoping there is something obvious I missed. Thanks!
