GGPK Viewer 3

GGPK Viewer 3 is a focused inspection tool for GGPK archives (version 3). It reads the archive structure, exposes a navigable index, and enables targeted extraction without modifying the source file. Conceptually, it parses the file header, builds a hierarchical index of blocks and entries, and exposes operations that rely on deterministic reading rather than editing. It benefits developers, modders, and researchers who need reproducible asset paths and quick visibility into large asset packs. Core value lies in reliability, version-awareness, and the ability to generate export manifests for tooling pipelines. Core features include listing, searching by path or extension, and selective extraction to a user-specified directory, plus optional integrity verification when checksums are present. It supports batch workflows by exporting a manifest of all accessible entries and their sizes. Use cases include verifying textures or models inside PoE GGPKs, extracting specific assets for analysis, or generating a structured asset inventory for modding or testing. The tool emphasizes correctness, traceability, and low setup friction, enabling researchers to work with complex archives without a full development environment.
It does not modify the archive and provides deterministic results suitable for automated pipelines. The v3 parser is designed to tolerate minor irregularities and report only accessible entries, ensuring safe exploration of large datasets with minimal risk.
