IMPLEMENTATION

Viewers responsible for this format

NPZ is a ZIP container whose entries are NPY arrays. Anyfile validates the archive, lists safe array members and opens selected numeric or structured values without unpickling Python objects.

Common question

Does Anyfile execute pickle data in NPZ files?

No. Object deserialization is intentionally disabled; only safe supported array layouts are inspected.
