How much Poka reads

B4 Summary. The container and metadata are read and summarised (counts, properties, structure), but the main content is not rendered.

Confidence: medium (the reviewer read the code). Basis: Reviewed 2026-10-26: read parsers/poka-vpk/src/main.rs (409 lines) and plugin.json. The three unit tests cover a well-formed tree, a tree that ends mid-entry (flagged) and an unsupported version; the corpus has no VPK. Covers .vpk and .vpk-valve. The table reads the version 1 or 2 header and walks the directory tree (extension, path, file name), giving one row per file with path, size, archive part, offset, CRC32 and preload bytes, with a summary of archives and top file types. Judgement: B4: the directory is listed but no file is extracted or shown.

What Poka does not read

  • File contents are not extracted or shown, including the data in the numbered archive parts
  • The version 2 MD5 sections and signature are not read or checked
  • CRCs are shown, not verified
  • Only the first 5,000 entries are listed
  • Files over 256 MiB are cut (flagged)
