If you want the most control (the "exclusive" insider method), use the Python script implementation.

Sometimes, a downloaded PSARC file has a corrupted header (often from FTP transfers). The exclusive version includes a that scans for the PSARC magic bytes ( PSAR followed by version) and rebuilds the index.

Some batch script extractors do not throw errors. They simply stop extracting when they hit an unknown compression block. You will think you extracted 1,000 files, but you actually only extracted the first 200. You then import those into your mod, and the game crashes because the table of contents is incomplete.

Use tool parameters to verify file structure before extraction. Conclusion
