I’ve been curious as to which graphical utilities for Linux desktops have got zstd support built in (to compress multiple files at a time). The default “Archive Manager” (3.30.1) which comes with my current MX Linux 19.2 XFCE doesn’t have zstd support yet.
After some searching, I’ve found and installed “PeaZip”, which is LGPL v3. It worked, however it was a bit clunky, because when you try to uncompress a .tar.zst (containing multiple files), you actually have to do 2 de-compressions. The first decompression merely extracts the .tar file. The second decompression actually extracts the multiple files out of the .tar file, like you were wanting in the first place. So that’s a bit awkward, but livable.
Note: It seems the gnome archive manager does support .zst files, but only in a newer version (current stable release is 3.36.4), which doesn’t yet come in MX Linux 19.2 (which is still based off Debian buster 10)! There doesn’t appear to be any snap for this newer version, either.
Anyone have any other graphical .zst file utilities they can recommend?
