Arma 3 Tools vs BSAOpt

Arma 3 Tools is a free Windows suite for producing content for the Real Virtuality engine used by Arma 3. Terrain Builder lets creators construct virtual worlds, while Object Builder creates, edits, and configures 3D models. Addon Builder converts source data into engine-readable formats and packages it into one archive; it can also sign PBOs with a digital key for secure servers. Publisher sends complete mods to Steam Workshop. Game Updater is intended to simplify switching between Steam branches, and Tools Launcher checks parts of an installation, runs suite tools, and can detect and interact with Mikero’s tools and Poseidon Tools. Distributed through Steam, the suite supports terrain, model, addon, mod, and script-related workflows, with PBO and FSM formats listed. Installation requires a valid Steam account, internet connection, and at least 1.1 GB of free disk space. Use is free for non-commercial work; commercial use requires Bohemia Interactive permission and acceptance of the BI Tools EULA.

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.
