These are two compression/archive fortmats that imo put to shame the well known 7z. The compression ration is better while taking less time to do compress and decompress adn they are multi threaded. I am actually surprise ark doe not support either.

Ark will support all formats that libarchive supports. Could you suggest these formats to this library?
Ark and libarchive already have lrzip support, so make sure you installed lrzip. From [1], you can see that Arch Linux lists lrzip as an optional dependency of Ark. [1] https://www.archlinux.org/packages/extra/x86_64/ark/

Welp according to this : https://github.com/libarchive/libarchive/wiki/LibarchiveFormats neither is supported.

Do you have the lrzip binary installed?
Ohh well libarchive it does has or used to have support for lrzip at least. Libarchive 3.1.0 Released: Jan 13, 2013 New features Added support for lrzip Added support for lzop Added support for grzip compression Added filters for base64 and uuencode Added support for writing tar v7 format Added support for resource-forks in Zip archives Added funtions to manually set filters and formats

Possibly libarchive has been compiled without lrzip supports. Please ask in the opensuse channels.
(In reply to Elvis Angelaccio from comment #8) > Possibly libarchive has been compiled without lrzip supports. Please ask in > the opensuse channels. I had no need to asked, support is there according to this : https://build.opensuse.org/package/live_build_log/Archiving/libarchive/openSUSE_Factory/x86_64 Ark just can't open .lrz files directly and for compression it needs to tar them 1st the same as lz4/zstd. I was using lrzip from the command line and using ark to open the resulting file, i was unaware ark could compress them as tar.lrz. I tested this it works fine, although ark does not exposes the other backends lrzip supoprts, i guess it uses the default one, lzma only. As for zpaq, i asked the question on the github still no answer.
zpaq support is still missing in Ark as far as I can see (zpaq package being installed). > As for zpaq, i asked the question on the github still no answer. @Tony could you point me that issue ? I can't find it.
