`zstd` is a compression program.

The zstd KIO worker is not directly usable, and is intended for use as a filter. For example, the tar KIO worker can filter a file through the zstd KIO worker, in order to display the contents of a `tar.zst` file directly in a &konqueror; window.

If you click on a file compressed with a `zst` extension in &konqueror;, this KIO worker is used to uncompress it and display it as a normal (uncompressed) file.

If you are a developer, and would like to use the zstd filter, you can find documentation on using KIO workers at http://techbase.kde.org

See the manual: zstd.
