7-Zip in 24 is adding zstd support so I will be archiving this.
7-Zip with additional algorithms, made portable. Windows x64 Sources: https://github.com/mcmilk/7-Zip-zstd + https://portableapps.com/apps/utilities/7-zip_portable & some needed modifications.
This works as described, but if you plan to install a file archiver I reccomend:
NanaZip: It's another 7zip fork, with zstandard and native Windows 11 context menu integration. https://github.com/M2Team/NanaZip
Peazip: a completely diferent FOSS archiver, multiplatofrm, with even more formats supported. But sometimes I have issues, with it not inputing/outputing consistently. It's best on Linux. https://github.com/peazip/PeaZip/releases/
