bz2-fastdl

This tool compresses files commonly used for game server fast download (FastDL) using bzip2 compression. It processes specified input directories, identifies files with relevant extensions, and outputs compressed versions (.bz2) to a designated output directory, preserving the relative directory structure.

Installation

Assuming you have Rust and Cargo installed, you can install bz2-fastdl directly from crates.io:

cargo install bz2-fastdl

Usage

bz2-fastdl -i <input_dir1> [input_dir2 ...] -o <output_root>

Arguments

• -i, --input-dir <INPUT_DIR>: One or more input directories to scan for files. The tool will recursively search these directories.
• -o, --output-root <OUTPUT_ROOT>: The root directory where the compressed files will be saved. The tool will create subdirectories within this root directory based on the base name of each input directory and the relative path of the original file.

Example

Suppose you have the following directory structure:

/path/to/game/materials/
├── file1.vmt
└── textures/
    └── texture1.vtf

/path/to/game/models/
└── player.mdl

To compress the files in materials and models directories and save them to /path/to/fastdl, you would run:

bz2-fastdl -i /path/to/game/materials /path/to/game/models -o /path/to/fastdl

This will create the following structure in /path/to/fastdl:

/path/to/fastdl/
├── materials/
│   ├── file1.vmt.bz2
│   └── textures/
│       └── texture1.vtf.bz2
└── models/
    └── player.mdl.bz2

Supported File Extensions

The tool currently compresses files with the following extensions:

• vmt
• vtf
• vtx
• phy
• mdl
• vvd
• wav
• mp3
• bsp
• nav

Files with other extensions will be ignored. Hidden files and directories (those starting with a .) are also skipped.
