dw ⚡

dw is a blazingly fast, parallel download accelerator written in Rust.

---

🚀 Installation

Getting dw is easy. You can choose any of the following methods.

From Crates.io (Recommended)

If you have the Rust toolchain installed, you can install dw directly from the official package registry:

cargo install dw-rs

From Source

If you prefer to build it yourself, you can compile dw directly from the source code:

git clone https://github.com/amirhosseinghanipour/dw.git
cd dw
cargo build --release

The executable will be in ./target/release/dw.

🏁 Getting Started

Using dw is straightforward. Here are the most common commands to get you started.

Basic Download

The simplest way to use dw is to just give it a URL. The tool will automatically figure out the filename and show you a progress bar while it downloads.

dw "http://cachefly.cachefly.net/100mb.test"

Saving with a Different Name

If you want to save the file with a different name, use the -o (or --output) flag.

dw "http://cachefly.cachefly.net/100mb.test" -o "100mb.zip"

🛠️ Advanced Usage

For those who want more control over the download process, dw offers several flags to fine-tune its behavior.

Change the Number of Connections

By default, dw uses 8 connections to download a file. You can increase or decrease this number with the -c flag to find the sweet spot for your network.

dw "http://cachefly.cachefly.net/100mb.test" -c 16

Adjust the Buffer Size

You can change the size of the memory buffer used for writing data to disk with the -b flag. The value is in kilobytes.

dw "http://cachefly.cachefly.net/100mb.test" -b 2048

Enable Adaptive Buffering

For a smarter download process, you can enable adaptive buffering with the --adaptive flag. When turned on, dw will automatically adjust its buffer size based on your real-time download speed.

dw "http://cachefly.cachefly.net/100mb.test" --adaptive

Set the Minimum File Size for Parallelism

dw is smart enough not to use its parallel download feature for very small files where it wouldn't be efficient. You can control this threshold with the --min-chunk flag, which sets the minimum file size (in megabytes) required to trigger a parallel download.

dw "[http://cachefly.cachefly.net/100mb.test](http://cachefly.cachefly.net/100mb.test)" --min-chunk 10
