7z format is more suitable for my task and actually not complex. Code is even more simple than in case if zip. Thanks for amazing 7zip.

update: ignore my notes about "Programmatic usage of xz lib", found error in my code and got size 37615 (FILTER_X86 and FILTER_LZMA2 for exe/dll files and only FILTER_LZMA2 for other files).

I tested, but -mm=xz doesn't work as expected. Etalon size (7zip format, not solid): 34.134 Programmatic usage of xz lib (https://github.com/addaleax/lzma-native) is not an option: size 45MB (no meta headers, only compressed file data concerted into one file) Strange, in general xz lib only slower than 7z, but result size should be not so different. (I use 7z l to see compressed size of files). 7-Zip 17.00 beta on Windows, -mm=lzma: 37.612 7-Zip 17.00 beta on Windows, -mm=xz: 37.619 -mm=xz doesn't...

So cool. Thanks a lot. p7zip 17.00 not yet released, I will try to find a way to update it.

Problem — I need to create archive in zip file format using xz compression. For what — to implement differential update like AppX does. 7z file format is complex, so, zip format is used and it wil be much easier to change it programmaticaly (i.e. download only changed blocks and update corresponding file in the archive). I see that I can use LZMA compression using -mm=lzma. But lzma doesn't support filters, and, as result, archive size is bigger compared to 7z format (in both cases solid archive...
