BSAOpt vs Game Extractor

BSAOpt is free, open-source Windows software for managing and recompressing BSA archives. It presents archive contents like directories, allowing files inside to be addressed directly, and can deduplicate files. Copy, Pack, Unpack, and Convert operations depend on the selected input and output. The listing says compression is roughly 5% better for files and 20% better for WAV files. Supported formats are BSA and ZIP, with archive extraction and mod packaging included. Version history lists Morrowind support, Fallout compatibility, and Xbox-type archives. Version 1.6.3 added recognition for XWM, FUZ, OGG, GID, and PEX files. Optional logs and a broken-header dialog can attempt recovery from corrupt BSAs. It is partially multi-threaded, supports 32-bit and 64-bit Windows Vista or later, and requires administrator execution when UAC is enabled. The listed version is 1.6.3, updated 14 January 2013.

Game Extractor is a Windows application for opening game archive files, viewing their contents, and extracting files to a PC. Its site says it supports archives from over 5,700 games across PC, mobile, and console platforms, including titles using Unity 3D, Unreal Engine, and Value Source Engines. The free Basic Version reads archives and extracts files. The one-time Full Version adds archive editing and saving, previews for many image, audio, and 3D mesh files, image and mesh conversion, and a format scanner for locating images and audio in unknown or unsupported archives. Supported formats include game containers, common archive and data files, and image and audio types. Optional FFmpeg and Java Media Framework integrations can extend preview support. Every version requires Java Runtime Environment 8 in its 32-bit form; the site says it comes with the application. Downloads are linked through GitHub and SourceForge. Tutorials are available as PDFs and videos, alongside in-program help. The site cautions that some supported games use archives its plugin cannot open, and edited archives are not guaranteed to work in games.
