The library used therefore is located here: [Multithreading Library](https:\u002F\u002Fgithub.com\u002Fmcmilk\u002Fzstdmt)\n\nYou can install it in two ways:\n1. complete setup with additions within the GUI and a modified Explorer context menu\n2. only the codec plugin that goes to your existing [7-Zip] installation (no GUI changes and no additional Hashers)\n\n# Status\n\n[![Latest stable release](https:\u002F\u002Fimg.shields.io\u002Fgithub\u002Frelease\u002Fmcmilk\u002F7-Zip-zstd.svg)](https:\u002F\u002Fgithub.com\u002Fmcmilk\u002F7-Zip-zstd\u002Freleases)\n[![PayPal.me](https:\u002F\u002Fimg.shields.io\u002Fbadge\u002FPayPal-me-blue.svg?maxAge=2592000)](https:\u002F\u002Fwww.paypal.me\u002FTinoReichardt)\n\n## Codec overview\n1. [Zstandard] v1.5.7 is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression \u002F speed trade-off, while being backed by a very fast decoder.\n   - Levels: 1..22\n\n2. [Brotli] v.1.2.0 is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.\n   - Levels: 0..11\n\n3. [LZ4] v1.10.0 is lossless compression algorithm, providing compression speed at 400 MB\u002Fs per core (0.16 Bytes\u002Fcycle). It features an extremely fast decoder, with speed in multiple GB\u002Fs per core (0.71 Bytes\u002Fcycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio.\n   - Levels: 1..12\n\n4. [LZ5] v1.5 is a modification of LZ4 which was meant for a better ratio at cost of slower compression and decompression. It's superseded by [Lizard] now.\n   - Levels: 1..15\n\n5. [Lizard] v2.1 is an efficient compressor with fast decompression. It achieves compression ratio that is comparable to zip\u002Fzlib and zstd\u002Fbrotli (at low and medium compression levels) at decompression speed of 1000 MB\u002Fs and faster.\n   - Levels 10..19 (fastLZ4) are designed to give about 10% better decompression speed than LZ4\n   - Levels 20..29 (LIZv1) are designed to give better ratio than LZ4 keeping 75% decompression speed\n   - Levels 30..39 (fastLZ4 + Huffman) adds Huffman coding to fastLZ4\n   - Levels 40..49 (LIZv1 + Huffman) give the best ratio, comparable to zlib and low levels of zstd\u002Fbrotli, but with a faster decompression speed\n\n6. [Fast LZMA2] v1.0.1 is a LZMA2 compression algorithm, 20% to 100% faster than normal LZMA2 at levels 5 and above, but with a slightly lower compression ratio. It uses a parallel buffered radix matchfinder and some optimizations from Zstandard. The codec uses much less additional memory per thread than standard LZMA2.\n   - Levels: 1..9\n\n### 7-Zip ZS CLI variants\n\n7z and 7zz provide largely the same core 7‑Zip functionality, but they are built\u002Fdistributed\ndifferently (plugin-capable vs. standalone), which can affect available formats\u002Fcodecs.\n\n| Binary | Description |\n|--------|-------------|\n| `7z`   | Full 7‑Zip command-line tool which loads it's modules\u002Fcodecs via 7z.so. |\n| `7zz`  | Official standalone 7‑Zip binary used on Linux\u002FmacOS packages - no external plugins via 7z.so. |\n| `7za`  | Standalone executable which supports fewer archive formats than `7z`. (Minimal + LZ4 and Hashes) |\n| `7zr`  | Minimal \"light\" standalone executable focused on the 7z format. (FLZMA2, Zstd) |\n\n## 7-Zip Zstandard Edition (full setup, with GUI and Explorer integration)\n\n### Installation (via setup)\n1. download the setup from here [7-Zip ZS Releases](https:\u002F\u002Fgithub.com\u002Fmcmilk\u002F7-Zip-zstd\u002Freleases)\n2. install it, like the default [7-Zip] one\n4. you may check, if the [7-Zip] can deal with [Zstandard] or other codecs via this command: `7z.exe i`\n\nThe output should look like this:\n```\n7-Zip 26.00 ZS v1.5.7 (x64) : Copyright (c) 1999- Igor Pavlov, 2016- Tino Reichardt, 2022- Sergey G.

normally, the x32 should go to: \"C:\\Program Files (x86)\\7-Zip\\Codecs\"\n   - the x64 version should go in here: \"C:\\Program Files\\7-Zip\\Codecs\"\n3. you could also replace the `7z.dll` directly within `C:\\Program Files (x86)\\7-Zip`\n4. then you may check if the dll is correctly installed via this command: `7z.exe i`\n\nThe output should look like this:\n```\n7-Zip 21.03 (x64) : Copyright (c) 1999-2021 Igor Pavlov : 2021-05-06\n\nLibs:\n 0  C:\\Program Files\\7-Zip\\7z.dll\n\nLibs:\n 0  c:\\Program Files\\7-Zip\\7z.dll\n 1  c:\\Program Files\\7-Zip\\Codecs\\brotli-x64.dll\n 2  c:\\Program Files\\7-Zip\\Codecs\\flzma2-x64.dll\n 3  c:\\Program Files\\7-Zip\\Codecs\\lizard-x64.dll\n 4  c:\\Program Files\\7-Zip\\Codecs\\lz4-x64.dll\n 5  c:\\Program Files\\7-Zip\\Codecs\\lz5-x64.dll\n 6  c:\\Program Files\\7-Zip\\Codecs\\zstd-x64.dll\n\n...\n\nCodecs:\n 0 4ED  303011B BCJ2\n 0  ED  3030103 BCJ\n 0  ED  3030205 PPC\n 0  ED  3030401 IA64\n 0  ED  3030501 ARM\n 0  ED  3030701 ARMT\n 0  ED  3030805 SPARC\n 0  ED    20302 Swap2\n 0  ED    20304 Swap4\n 0  ED    40202 BZip2\n 0  ED        0 Copy\n 0  ED    40109 Deflate64\n 0  ED    40108 Deflate\n 0  ED        3 Delta\n 0  ED       21 LZMA2\n 0  ED    30101 LZMA\n 0  ED    30401 PPMD\n 0   D    40301 Rar1\n 0   D    40302 Rar2\n 0   D    40303 Rar3\n 0   D    40305 Rar5\n 0  ED  6F10701 7zAES\n 0  ED  6F00181 AES256CBC\n 1  ED  4F71102 BROTLI\n 2  ED       21 FLZMA2\n 3  ED  4F71106 LIZARD\n 4  ED  4F71104 LZ4\n 5  ED  4F71105 LZ5\n 6  ED  4F71101 ZSTD\n```\n\n### Usage (codec plugin)\n\n- compression and decompression for [Brotli], [Fast LZMA2], [Lizard], [LZ4], [LZ5] and [Zstandard] within the 7-Zip container format\n- you can only create `.7z` files, the files like `.lz4`, `.lz5` and `.zst` are not covered by the plugins\n- when compressing binaries (*.exe, *.dll), you have to explicitly disable the bcj2 filter via `-m0=bcj`,\n  when using only the plugin dll's\n- so the usage should look like this:\n```\n7z a archiv.7z -m0=bcj -m1=zstd -mx1   Fast mode, with BCJ preprocessor on executables\n7z a archiv.7z -m0=bcj -m1=zstd -mx..  ...\n7z a archiv.7z -m0=bcj -m1=zstd -mx21  2nd Slowest Mode, with BCJ preprocessor on executables\n7z a archiv.7z -m0=bcj -m1=zstd -mx22  Ultra Mode, with BCJ preprocessor on executables\n7z a archiv.7z -m0=bcj -m1=brotli -mxN  ...\n7z a archiv.7z -m0=bcj -m1=lizard -mxN  ...\n7z a archiv.7z -m0=bcj -m1=lz4 -mxN  ...\n7z a archiv.7z -m0=bcj -m1=lz5 -mxN  ...\n7z a archiv.7z -m0=bcj -m1=flzma2 -mxN  ...\n```\n\n## Codec Plugin for Total Commander\n\nThere is no dedicated plugin for [Total Commander](https:\u002F\u002Fwww.ghisler.com\u002F) anymore,\nand it seems that the files `tc7z.dll` and `tc7z64.dll` cannot simply be replaced at the moment.\n\n## Codec Plugin for Far Manager\n- copy the `7z.dll` file from `C:\\Program Files\\7-Zip-Zstandard\\7z.dll` to `C:\\Program Files\\Far Manager\\Plugins\\ArcLite\\7z.dll`\n- then restart the Far manager - and on next start, you will have support for 7-Zip Zstandard archives ;-)\n\n## Benchmarks\n\nFor benchmarking, I started using the Linux binary `7zz` in 2026.\n\nThe test system is an idle Dell PowerEdge R6615 with the following hardware:\n- **CPU:** AMD EPYC 9354P (32 cores)\n- **Memory:** 128 GB DDR5 (8x 16GB)\n- **OS:** AlmaLinux 9 (x86_64)\n\nFor the tests, the [Silesia compression corpus](https:\u002F\u002Fsun.aei.polsl.pl\u002F~sdeor\u002Findex.php?page=silesia) is used.\n\nCompression tests are performed by running a single-threaded compression for each method: `7z a test.7z -mmt=1 -m0=MethodX`.\n\nDecompression is tested on the freshly created archive using: `7z t test.7z`.\nMemory usage and execution times are measured using a [modified GNU time](https:\u002F\u002Fgithub.com\u002Fmcmilk\u002F7-Zip-Benchmarking\u002Fblob\u002Fmaster\u002Flinux\u002Ftime-1.9.tr.diff).\nThe benchmarks themselves are executed via a [shell script](https:\u002F\u002Fgithub.com\u002Fmcmilk\u002F7-Zip-Benchmarking\u002Fblob\u002Fmaster\u002Flinux\u002Fruntests.sh).\n\nResults:\n\n![Compression Speed vs Ratio](https:\u002F\u002Fmcmilk.de\u002Fprojects\u002F7-Zip-zstd\u002Fdl\u002F2026-01-03\u002F01-ratio-vs-compr.png \"Compression Speed vs Ratio\")\n![Decompression Speed vs Ratio](https:\u002F\u002Fmcmilk.de\u002Fprojects\u002F7-Zip-zstd\u002Fdl\u002F2026-01-03\u002F02-ratio-vs-decompr.png \"Decompression Speed vs Ratio\")\n![Decompression Speed](https:\u002F\u002Fmcmilk.de\u002Fprojects\u002F7-Zip-zstd\u002Fdl\u002F2026-01-03\u002F03-compr-per-level.png \"Compression Speed per Level\")\n![Decompression Speed](https:\u002F\u002Fmcmilk.de\u002Fprojects\u002F7-Zip-zstd\u002Fdl\u002F2026-01-03\u002F04-decompr-per-level.png \"Decompression Speed per Level\")\n![Memory at Compression](https:\u002F\u002Fmcmilk.de\u002Fprojects\u002F7-Zip-zstd\u002Fdl\u002F2026-01-03\u002F05-mem-compr.png \"Memory usage at Compression\")\n![Memory at Decompression](https:\u002F\u002Fmcmilk.de\u002Fprojects\u002F7-Zip-zstd\u002Fdl\u002F2026-01-03\u002F06-mem-decompr.png \"Memory usage at Decompression\")\n\n## Themes\n\n- FileManager Toolbar Icon Theme: Glyfz 2016 by AlexGal [homepage](https:\u002F\u002Fwww.deviantart.com\u002Falexgal23)\n- File Types Icon Theme: Windows 10 by masamunecyrus [homepage](https:\u002F\u002Fwww.deviantart.com\u002Fmasamunecyrus)\n- Additional icons file types created by Mr4Mike4 [homepage](https:\u002F\u002Fgithub.com\u002FMr4Mike4)\n- Dark mode support via darkmodelib (v0.47.0) by ozone10 [homepage](https:\u002F\u002Fgithub.com\u002Fozone10)\n\n## License and Redistribution\n\n- The same as the Mainline [7-Zip], which means most of the code is GNU LGPL v2.1-or-later\n- Read [COPYING](COPYING) for more details\n\n## Links\n\n- [7-Zip Homepage](https:\u002F\u002Fwww.7-zip.org\u002F)\n- [7-Zip Zstandard Homepage](https:\u002F\u002Fmcmilk.de\u002Fprojects\u002F7-Zip-zstd\u002F)\n- [Request for inclusion](https:\u002F\u002Fsourceforge.net\u002Fp\u002Fsevenzip\u002Fdiscussion\u002F45797\u002Fthread\u002Fa7e4f3f3\u002F) into the mainline 7-Zip:\n  -
