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-adf/src/main.rs (569 lines) and plugin.json. The three unit tests check that ArcInfo grid files sharing the extension are named, not that disks are read; the corpus has ADFlib_testofs.adf but no test reads it. Covers .adf. The tree reads the boot block (OFS or FFS, international and directory-cache flags), the root block (disk name, creation and modification dates) and walks the hash tables recursively, listing directories and files with their sizes. Judgement: B4: the file tree is listed but no file is extracted or shown.

What Poka does not read

  • File contents are not extracted or shown
  • File dates, protection bits and comments are not shown
  • Soft and hard links are listed as unknown entries
  • The boot block code and checksum and the free-space bitmap are not read
  • Non-DOS disks (custom loaders, PFS) and hard-disk images are refused
  • Caps of 2,000 entries, 32 levels and 4 MiB (flagged)
