Modded 7zip For Lz4 Link
| Tool | LZ4 support | Archive format | |------|-------------|----------------| | PeaZip | Yes (full) | .7z, .lz4 | | WinRAR | No (but fast modes) | .rar | | lz4.exe (official) | Yes | .lz4 only | | 7-Zip ZS | Yes (unofficial fork) | .7z, .lz4 |
7-Zip ZS (by mcmilk) already adds LZ4, LZ5, Zstd, and Brotli to 7-Zip. You can find it on GitHub.
Let's test a realistic scenario. Source: A Logs folder (2,000 .txt files, Total size: 512 MB). modded 7zip for lz4
| Tool | Algorithm | Time to Compress | Final Size | Time to Decompress | | :--- | :--- | :--- | :--- | :--- | | Official 7-Zip | LZMA (Normal) | 18.4 seconds | 89 MB | 4.2 seconds | | Official WinRAR | RAR5 | 12.1 seconds | 102 MB | 3.1 seconds | | Modded 7-Zip | LZ4 | 0.9 seconds | 211 MB | 0.4 seconds |
Conclusion: The modded LZ4 archive is 2.3x larger than LZMA, but it compressed 20x faster. For temporary archives or backups over 10Gbps LAN, speed wins. | Tool | LZ4 support | Archive format
For decades, 7-Zip has been the gold standard of file compression. Its native LZMA algorithm offers an unparalleled compression ratio, making it the go-to tool for archiving and sharing data. However, in the world of IT, game development, and data engineering, there is a crucial trade-off: speed versus size.
Standard 7-Zip is slow. Compressing a 10GB virtual machine image or a folder of high-resolution textures using LZMA can take minutes. 7-Zip ZS (by mcmilk) already adds LZ4, LZ5,
Enter the niche but powerful concept of a modded 7zip for LZ4. While Igor Pavlov’s official 7-Zip does not natively support the LZ4 algorithm, the open-source community has stepped in. They have created modified forks (modded versions) that integrate LZ4—a compression algorithm designed for sheer velocity.
This article explores why you need a modded 7-Zip, how LZ4 revolutionizes workflow efficiency, and where to find the safest builds.
If you run a local SQL database or a VM sandbox, dumping the folder to an LZ4 7z file takes seconds, minimizing downtime.
