.ZST files are compressed using Zstandard, an efficient compression algorithm used especially for backups. It provides both a very high compression ratio and is very secure in keeping files intact. If you need to unzip ZST files on macOS, this short tutorial will be very useful to you.
How can you unzip ZST files on macOS cu Homebrew
In the previous tutorial I showed step by step how you can install Homebrew on computers macOSIn this tutorial we will use a ZSTD application installed using Homebrew to unzip .zst files without needing a GUI application. We will do everything from command lines executed in the Terminal utility.
So, the steps are as follows:
1. Open Terminal and install Homebrew, if you don't have it installed already. It only takes 2 minutes with this tutorial.
2. Install the ZSTD application via the command line:
brew install zstd
The installation only takes a few seconds, and at the end you should have something similar to the image below on your screen:

3. Navigate with the command “cd
" in the folder where you have the file .zst
what is about to be unarchived.
cd /path/to/file.zst
4. Run the file unzip command with:
zstd -d file.zst
In my example I had to unzip the file ihowto.tips.zst
.

In many situations, after unzipping a ZTS file, an archive is obtained .tar
To unzip it use the command:
tar -xvf file.tar
This is the easiest way to unzip ZST files on Mac computers, without the need to install a graphical interface application.
