Open ZST Compression File

1

Does anyone know of an app that opens *.zst compressed file on a Mac?

I never heard of ZST. It seems to be a compressed file using Facebook’s ZStandard algorithm.

If the usual unarchiver apps are not able to uncompress the file, you can do so using the terminal.

  1. Install Hombrew (if you have not already): https://www.howtogeek.com/211541/install-homebrew-on-mac/

  2. Install zstd via Terminal: brew install zstd

  3. Navigate to the file in question using the Terminal or right click on the folder where the file is located at (–> Services) → New Terminal at Folder

  4. Uncompress the file using the Terminal: zstd -d yourfilename.tar.zst

Done.

According to Facebook, PeaZip is an app that supports ZST files:

I never have heard of PeaZip, either. It may be an idea to just stick with the Terminal.

A YouTube video showing the use of the Terminal (note: Homebrew needs to be installed).

I had not heard of it either. Command Line and Terminal stuff is a bit beyond my comfort zone. Tried what you suggested and it threw some errors. May pass on this whole thing.

PeaZip is a rather well-known open source archiver that supports encryption and is often recommended (for example when creating exports from password managers – it is mentioned in the official backup guides for Bitwarden, for example) and is safe to use.

cc @sgclark It has a UI, no need to use the terminal.
