Once you have the tool ready, there are several advanced scenarios and features to explore to maximize the utility of the LZ4 codec.

If you replaced your standard 7-Zip, file associations (like .7z or .zip ) should automatically point to the new version. If you installed it alongside, you may need to right-click a file -> "Open with" -> Choose the 7zFM.exe from the ZS folder. modded 7zip for lz4

Here’s an interesting, concise write-up on the topic:

Understanding the technical specifications is one thing; knowing when to deploy LZ4 is another. Here are three specific scenarios where a modded 7-Zip with LZ4 excels.

Choose native LZMA2 for long-term archiving where disk space is premium. Choose modded LZ4 for daily backups, game mod packaging, software development builds, and hot-tier data storage where time is the primary constraint.

For fast decompression with varying compression levels. Key Benefits of Modded 7-Zip with LZ4 1. Incredible Decompression Speeds

While algorithms like LZMA2 squeeze files down to the smallest possible footprint, they require significant time and CPU cycles. LZ4 takes the opposite approach. It offers a moderate compression ratio but processes data almost as fast as your storage drive can read and write it. Ideal Use Cases

But vanilla 7‑Zip doesn’t speak LZ4 out of the box. It focuses on LZMA, LZMA2, PPMd, and BZip2 — all slower but denser. Here’s an interesting, concise write-up on the topic:

In modern computing, we often need to compress logs as they are generated (file rotation). Using LZMA2 for this creates a significant CPU spike. LZ4's lightweight nature means you can run compression in the background constantly without slowing down your application.

In standard 7-Zip, the CPU is usually the bottleneck. With modded LZ4, the bottleneck almost always shifts to your Drive I/O (Disk Speed)
