VPK extractor

This tool enables inspection and extraction of Valve Pak archives without a game engine. It reads VPK headers, reconstructs the virtual file tree, and exposes file entries and their attributes for review.
Conceptual workflow involves providing a VPK file, choosing between full extraction or metadata listing, and receiving a structured manifest plus extracted payload. It preserves the original directory structure and reports progress, integrity checks, and any anomalies encountered during processing.
Who benefits includes game modders, asset researchers, developers, and QA teams working with Steam games. The tool adds value through strict VPK format validation, optional selective extraction by file type or extension, and post extraction integrity validation. Typical use cases cover asset auditing, dependency mapping, and preparing assets for tooling pipelines in automated workflows.
Core features include header validation, directory reconstruction, handling of both compressed and uncompressed entries, and safe error handling with clear signals when extraction cannot complete. Outputs include an organized file tree manifest, optional per-entry metadata, and a bundle of extracted assets ready for downstream processing.
