The most prominent "modded" version of 7-Zip that integrates

While the official 7-Zip build is great, it lacks native support for

This flexibility allows you to test the new codecs in your existing workflow without any major commitment.

Mainline 7-Zip does not natively support the LZ4 algorithm. To use it, you must install a custom modification or a third-party plugin framework designed to insert the missing codecs.

Standard 7-Zip is slow. Compressing a 10GB virtual machine image or a folder of high-resolution textures using LZMA can take minutes.

Beyond packing LZ4 into a .7z container, these modded forks often support direct handling of the native .lz4 format. If you come across a standalone file compressed with the LZ4 algorithm (such as those created by the standalone lz4 CLI tool), programs like NanaZip or 7-Zip ZS can open and extract them directly without needing to wrap them in a 7z archive first. This is particularly useful in development pipelines where raw LZ4 framing is preferred.

If you are suffering from slow backup windows, if your game load times are too long, or if you simply want to manage your local files with the highest possible throughput, downloading a modded 7-Zip build is a worthwhile investment. You gain access to a toolkit that allows you to choose your weapon: LZMA2 for archival storage or LZ4 for raw, blistering speed. In the world of file management, having both options at your fingertips is the ultimate power move.

To use LZ4 within the familiar 7-Zip interface ( .7z container), you need a custom build. The most reputable and widely used version is 7-Zip-zstd by mcmilk, which integrates multiple modern codecs.

This is where comes in. Created by Yann Collet, LZ4 is a lossless compression algorithm focused entirely on extreme speed, operating near the limits of RAM subsystems.

To use LZ4 with 7-Zip, you need an enhanced version. The most popular is (often called 7-Zip-zstd).

7z a -mm=LZ4 -mx=3 output.7z input_folder

The most prominent and trusted fork for this purpose is (also known as the Modern 7-Zip variant). This modded version seamlessly integrates several modern compression algorithms into the standard 7-Zip framework, including: LZ4: For ultra-fast speed.

The official release of 7-Zip natively supports a limited set of compression methods: LZMA, LZMA2, PPMd, BZip2, and Deflate. While LZMA2 provides exceptional compression ratios, it is incredibly CPU-intensive and slow. If you regularly compress multi-gigabyte datasets, log files, or game assets where speed matters more than saving every last kilobyte, stock 7-Zip bottlenecks your workflow. The Modded Solution

By using a modded version like 7-Zip ZS, users gain access to specialized tools for different data scenarios:

Since the official 7-Zip doesn't natively support LZ4, developers like and the team at tc4shell took matters into their own hands:

LZ4 isn’t about maximum compression — it’s about blazing speed. Designed by Yann Collet, LZ4 trades raw ratio for throughput measured in GB/s. It’s the go‑to for real‑time scenarios: game asset streaming, database backups, RAM snapshots, and even Linux kernel decompression.
