What is a TZST file? A TZST file is a compressed archive that combines the TAR and Zstandard formats. It contains multiple files and folders bundled into a single Tape Archive ( .TAR file), which preserves the original directory structure and file metadata . The resulting TAR archive is then compressed using the Zstandard (zstd) compression algorithm to reduce its size.

More Information Developers, system administrators, and Linux users most often work with TZST files, especially when handling repositories, system images, or archived project files. The file type is commonly used in Unix and Linux environments for distributing software packages, sharing source code, creating backups, and storing large collections of files. NOTE: The .tzst extension is a shortened form of the .tar.zst ( .TAR.ZST file), similar to how .TGZ , .TBZ2 , and .TXZ represent compressed TAR archives.

How to open a TZST file

You can open TZST files by decompressing them with a Zstandard-compatible tool, such as Zstandard ot the zstd command-line utility, and then extract the resulting TAR archive using standard tar commands. On Linux, this can be done in one step using:

tar --zstd -xf archive.tzst

On Windows and macOS, you can use third-party utilities, such as PeaZip and Bandizip, to decompress and extract TZST files. After extraction, the original files and folders are restored in their saved structure.
