|
||||
This is the Github Page of 7-Zip with support for **zstd**, short for
|
||||
Zstandard, which is a fast lossless compression algorithm, targeting
|
||||
real-time compression scenarios at zlib-level compression ratio.
|
||||
|
||||
You can install it in two ways:
|
||||
1. A full setup with ZStandard additions within the GUI and an modified
|
||||
Explorer context menu
|
||||
2. just the codec plugin, which goes to your existing 7-Zip installation
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
# 7-Zip ZStandard Edition (full setup, with GUI and Explorer integration)
|
||||
|
||||
## Installation
|
||||
|
||||
1. download the setup from here https://mcmilk.de/projects/7-Zip-zstd/dl/
|
||||
- https://mcmilk.de/projects/7-Zip-zstd/dl/7z1602-zstd-x32.exe
|
||||
- https://mcmilk.de/projects/7-Zip-zstd/dl/7z1602-zstd-x64.exe
|
||||
2. install it
|
||||
|
||||
## Usage
|
||||
|
||||
|
||||
|
||||
|
||||
# ZStandard codec Plugin for 7-Zip
|
||||
|
||||
## Installation
|
||||
|
||||
1. download the codec archiv from https://mcmilk.de/projects/7-Zip-zstd/dl/Codecs.7z
|
||||
2. create a new directory named "Codecs"
|
||||
3. put in there the zstd-x32.dll or the zstd-x64.dll, depending on your 7-Zip installation
|
||||
- normally, the x32 should go to: "C:\Program Files (x86)\7-Zip\Codecs"
|
||||
- and the x64 version should go in here: "C:\Program Files\7-Zip\Codecs"
|
||||
4. After this, you may check if the dll is correctly installed via this command: `7z.exe i`
|
||||
|
||||
The output should look like this:
|
||||
```
|
||||

|

```
|
||||
|
||||
## Usage
|
||||
|
||||
- when compressing binaries (*.exe, *.dll), you have to explicitly disable
|
||||
the bcj2 filter via `-m0=bcj`
|
||||
|
||||
- so the usage should look like this:
|
||||
```
|
||||
7z a archiv.7z -m0=bcj -m1=zstd -mx0 ...Fastest Mode, without BCJ preprocessor
|
||||
7z a archiv.7z -m0=bcj -m1=zstd -mx1 ...Fast mode, with BCJ preprocessor on executables
|
||||
7z a archiv.7z -m0=bcj -m1=zstd -mx.. ...
|
||||
7z a archiv.7z -m0=bcj -m1=zstd -mx21 ...2nd Slowest Mode, with BCJ preprocessor on executables
|
||||
7z a archiv.7z -m0=bcj -m1=zstd -mx22 ...Ultra Mode, with BCJ preprocessor on executables
|
||||
```
