What is a TZST file?

TZST files mostly belong to Duplicati. TZST files are Zstandard compressed tarball archives used mainly by the backup software Duplicati.
This file format works by first grouping files together into a tar archive (a tarball) and then applying the Zstandard compression algorithm to reduce the file size. This method is popular for backing up data because it efficiently compresses large sets of files while maintaining quick decompression speeds.
Consider these details:

Purpose: Stores backup data in a single, compressed file.

Functionality: Bundles files into a tar archive and compresses them with Zstandard.

Compatibility: Primarily used by Duplicati, but can also be handled by command-line tools (like zstd) and compatible tar utilities.

FilExt.com tip: For additional support, visit the Duplicati website.

A *.TZST file is a tarball compressed using the Zstandard algorithm. A tarball (or tar archive) is a single file containing multiple files and directories, often used for archiving and distribution. Zstandard (or zstd) is a fast lossless compression algorithm designed for high compression ratios and speed. The *.TZST extension signifies that the file is a tar archive that has been compressed using zstd. This combination offers efficient storage and transfer of archived data. This file format is classified as Compressed Archive.
