however, only about half the files are present.

i'm comparing zimmer's output to that of the following Zim extractor, written in Rust: https://github.com/dignifiedquire/zim

you can see from the screenshot above that Rust extracts 3.9G of HTML and images, while zimmer extracts 1.7G from the same dump file

spot checking a few specific articles:

the Rust extractor extracts five articles that start with "Hyperte", while zimmer extracts three:

Research direction

Reproduce extraction of the Simple English Wikipedia dump with zimmer and compare its output with the Rust ZIM extractor linked in the issue. Inspect zimmer's ZIM parsing and extraction entry points, focusing on why the two Hypertext_Markup_Language articles and other files are omitted; done means the missing articles are extracted.
