It would be great to see support added for Facebook's zstd (aka zstandard), extension `.zst`. Repo: https://github.com/facebook/zstd
zstd is no archive format. Do you need to decompress a *.tar.zstd file?
(In reply to Christoph Feck from comment #1) > zstd is no archive format. Do you need to decompress a *.tar.zstd file? zstd can compress input into .zst file. To compress directories I've used it with tar to get a tar.zst file, followed with tar and zstd commands to decompress.(plus split/cat if creating multi-part files). Any support would be good :)
zstd support was recently merged in the libarchive git repo. So after next libarchive release we can easily add zstd support in Ark.
libarchive 3.3.3 was released in September, can this feature be pucked up?
I've seen that work has been done already https://phabricator.kde.org/D15369 That's great, thanks!
Git commit d876ba3d9ebc8f00c2b0b06c9c8bd60c824aa563 by Ragnar Thomsen. Committed on 06/11/2018 at 16:20. Pushed by rthomsen into branch 'master'. Add support for Zstd-compressed Tar-archives Libarchive 3.3.3 was released on 2018-09-04 and added support for the Zstandard compression filter. This compression method is designed to give similar compression ratio as gzip but with much greater (de)compression speeds. Libarchive uses the libzstd.so library, but seems to use the zstd binary as fallback if it wasn't built with libzstd. This diff enables the filter in the libarchive plugin. There is still no mimetype in shared-mime-info, so a custom mimetype for zstd-compressed tar archives is added. This necessitated re-adding functionality in Ark for custom mime-types (was removed in commit 73cd5e8d2e7b347d84438b23afdc892eddb78ed2). Support is only enabled when built with libarchive>=3.3.3.
