(often found as ) is a multi-threaded precompression and preprocessing tool developed by Razor12911
. It is primarily used by game repackers (like FitGirl) to significantly reduce the size of game files before archiving, allowing for faster downloads and installations. Core Functionality
XTool works by identifying compressed data within files (like Zlib, Oodle, or LZ4 streams) and "decompressing" them into a raw format that standard archivers can compress more effectively. Multi-threading
: Unlike many older tools that use only one CPU thread, XTool can utilize all available system threads to speed up the process.
: Supports various compression libraries including Zlib, Oodle, LZ4, Zstd, and Gdeflate.
: The tool is generally considered safe and is a standard part of many well-known game repacks. Basic Command Syntax If you are using the command-line version from the Razor12911 GitHub repository , the standard usage follows this pattern:
XTool [command]:[operation]:[options]:[codecs] [input] [output] Encode (Precompress data) Decode (Restore data to original state) Example Command
XTool e:precomp:c32mb,t4:zlib,lz4 InputFile.data OutputFile.xtl This command encodes InputFile.data using a 32MB chunk size ( ), 4 threads ( ), and looks for Zlib and LZ4 streams. Common Issues High CPU Usage
: Because it is designed to be as fast as possible, it will often use 80%–100% of your CPU during a game installation. This is normal behavior for the tool. Task Manager
: If the process hangs after an installation finishes, you can safely end the task in Task Manager.
: Some antivirus programs may flag it as a "false positive" due to its association with game repacks. It is common to add the installation folder to your exclusion list if you trust the source.

Installation Guide: Upgrading to the Xtool Razor12911
Because the "12911" is often a replacement or upgrade part, installation differs from buying a new machine. If you have acquired this module, follow these steps: Strong cutting ability for a diode laser Precise
Step 1: Power Down & ESD Safety Disconnect the Xtool mainboard power. The Razor's dual-diode driver is sensitive to electrostatic discharge. (Always wear a strap).
Step 2: Removing the Old Laser Head Unplug the 4-pin and 7-pin ribbon cables from your existing module. Loosen the eccentric nut on the roller plate to slide the old module off the X-axis rail.
Step 3: Mounting the Razor12911 The Razor12911 uses a proprietary quick-release clamp. Slide it onto the rail until it clicks. Do not over-tighten; you want 1mm of lateral play for the belt tensioner.
Step 4: Firmware Update (Crucial!) Standard Xtool LightBurn software does not recognize the "Razor" power curve. You must flash the custom "Razor12911 firmware" (available via Xtool’s Parts Archive). Failure to do so will result in the laser firing at 50% power regardless of settings.
Step 5: Focus Calibration Place the provided metal focus gauge (2.5mm thick) between the material and the nozzle. Lower the module until the gauge just touches the material surface. Tighten the thumb screw.
