One of the defining features of xTool is its versatility and modularity. It supports a wide array of filters and algorithms, including those for processing Zlib, LZ4, and various game-specific encryption methods. Because it is lightweight and highly optimized, it can handle large volumes of data without becoming a bottleneck in the repacking workflow. This efficiency is critical for community members who distribute "repacks," as it ensures that the end-user can decompress and install the software in a reasonable timeframe despite the heavy underlying compression.
