Zstandard is also part of zip format since 2020
See https://en.wikipedia.org/wiki/ZIP_(file_format) with Pkzip format 6.3.8 available at 93 since 2020.
so my question here: is this supported in p7zip? Or an older state of zip without zstandard?
This issue is a duplicate of #25.
master
branch supports Zstd in ZIP (0ecdf74), but the other two branches do not support it yet.
You can also try https://github.com/cielavenir/p7zip , which is based on 7-Zip 22.00. cielavenir's fork supports Zstd in ZIP format and also other additional codecs in 7z format.
you can use https://github.com/jinfeihan57/p7zip/releases/tag/v17.04 or https://github.com/cielavenir/p7zip/releases/tag/22.00.1 out of box
if you still want classic p7zip, extract cielavenir/p7zip/releases/tag/22.00.1 and copy Codecs directory to the same directory as 7z.so (note that this method only supports decompression)
I my opinion of a little user, it should be possible in the two ways zip-93-Mode and zstd. So the user has no problems with actual zip with zstd codec in zip-container. And the user should can use normal zstd way. That was my deeper intention. That is than here a duplicate in code, but the world is not perfect.
Administrators can reduce with change to zstd inside the size of zip-files and more performance for user a lot without changing name of file. There is a great adavantage here on old zip area with zip93 possibility It need only actual zip standard.
Thanks for your great work.
Try this branch.
Great news, everyone! Igor Pavlov is working on Zstd support (for both 7z and zip formats, and probably for others like RPM too)!
