IMPLEMENTATION

Viewers responsible for this format

CB7 uses the 7z container for a sequence of comic images. Solid archives can share compression across several entries, so reading an arbitrary later page may depend on decoding earlier data. Anyfile performs bounded sequential extraction once and then reads pages from the local extracted source.

Common question

Why can a small CB7 archive exceed the size limit?

Compressed size and expanded image bytes are different. The reader limits cumulative extraction to 128 MiB even when the 7z file itself is below the 128 MiB input limit.

Does every CB7 page jump decompress the solid archive again?

No. After the initial extraction, navigation reads locally stored encoded images. The reader decodes only the active image neighborhood rather than all pages at once.
