Hi, > Its customary file extension is ".zst", while some tools use ".tzst" > as a shorthand for ".tar.zst".
This shortening should die, just like DOS 8.3 filenames. If it's .tar.foo then eyeballs and scripts stand a chance of realising it's a tar file that's had another transformation applied, and that's what they have to undo first; with an unadulterated suffix as a clue. Knowing .tng is a next-generation compression program applied to a tar file, rather than the next generation in file formats, is tedious and creates duplication where none is needed. Let's not repeat past mistakes when the constraints have bit the dust. -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
