About the ZST format
ZST is Zstandard, Facebook’s compressor that reaches gzip-class ratios at an order of magnitude more speed. Database dumps (MySQL, PostgreSQL), game assets and modern log pipelines increasingly deliver .zst files.
Its weak spot is desktop support: few archive GUIs read it yet, so a ZST usually has to be unpacked and repacked before it is useful to anyone else.
