xtool is an open-source tool for detecting, decoding, repacking and manipulating compressed/encrypted/data streams inside files (game archives, executables, resources). It’s written primarily in Pascal, distributed under the MIT license, and maintained by Razor12911 (GitHub). The repo was archived (read‑only) by the author; latest major release series is 0.6.x–0.7.x.
To understand the value of the xtool library, one must first understand the problem of digital distribution. High-definition textures, lossless audio, and sprawling open-world game assets often consume hundreds of gigabytes. Distributing such files over the internet requires either massive bandwidth or extreme compression. Traditional archivers like ZIP or RAR reach a limit where they cannot further reduce file size without corrupting data. This is where razor12911’s work enters the fray. xtool library by razor12911 verified
