Assumptions
(using Template:Message) I've been doing some reverse engineering/code research and a few assumptions made in this article are incorrect:
- The ArchiveIndex, EntryOffset, and EntryLength fields of VPKDirectoryEntry can be repeated if a file has fragmented contents. This explains why there is a terminator at the end of the entry header.
- In CPackedStoreFileHandle (Alien Swarm SDK) the data referred to by the article as "Preload" is referred to as "Metadata" instead. The actual file data and the metadata are never mixed, so the comment about vmt files being stored entirely in the directory is incorrect.
