Warning : the experimental target zstdmt contained in this release has an issue when using multiple threads on large enough files, which makes it generate buggy header. While fixing the header after the fact is possible, it's much better to avoid the issue. This can be done by using zstdmt in pipe mode : cat file | zstdmt -T2 -o file.zst This issue is fixed in current dev branch, so alternatively, create zstdmt from dev branch.

Note : pre-compiled Windows binaries attached below contain the fix for zstdmt
