BSAOpt vs WolvenKit

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.

WolvenKit is a free, open-source modding tool focused on Cyberpunk 2077 and REDengine 4. It can browse, extract, modify and repack game files into archives for use in the game. The Asset Browser previews meshes and textures from base-game or user-generated archives. Its RTTI-based File Editor reads and saves REDengine files, handles in-place buffer data, and converts game files to human-readable JSON and back. Project Explorer organizes files and opens source assets such as blend, PSD and XCF files. Asset conversion tools cover listed texture and model formats, with Blender one-click imports for shaded Cyberpunk meshes. Stable and nightly builds come through GitHub releases. Windows 10/11 64-bit and Linux are supported, although Linux compatibility is described as unstable and not guaranteed. The latest .NET 10.0 runtime and x64 architecture are required.
