Microsoft is (finally) adding native support for tar/gz/bz2/rar/7z (edit: and xz/zstd) to Windows, so third party apps shouldn't be required for much longer. https://blogs.windows.com/windows-insider/2023/08/18/announcing-windows-11-insider-preview-build-22621-2199-and-22631-2199-beta-channel/ https://blogs.windows.com/windows-insider/2023/08/18/announc... It's only available on the preview channel for now but it's coming.

Command line support for these formats has existed in Windows for multiple years via bsdtar which has shipped with Windows for quite a while now.

    The comment originally mentioned tar/gz/bz2/rar/7z support being added to Windows. bsdtar supports all of these.

      bsdtar is backed by libarchive, which supports all the formats listed at https://github.com/libarchive/libarchive/wiki/LibarchiveFormats https://github.com/libarchive/libarchive/wiki/LibarchiveForm...

Have they added lz4 and xz as well?

  Please, not even Linux distros add those by default yet. Microsoft won't consider it until at least 2030.

  I don't have a preview channel install handy to check, but they're using libarchive so here's the full list assuming they expose everything it supports: https://github.com/libarchive/libarchive#supported-formats https://github.com/libarchive/libarchive#supported-formats edit: amended my last reply, Microsofts latest blog post says that XZ and Zstd are also supported.

    Great, a new attack vector. Don't get me wrong, I love that they add support for more open source formats, but decompressors (especially written in C) are one of the most common sources of bugs basically everywhere. I wish they would sandbox it, but they probably won't.

      Having the decompressor updated automatically by Windows Update is a significant step up from the current status quo of installing WinRAR or 7zip once and then usually never updating it for years because it has to be done manually. Microsoft will probably have more diligence in hardening the binaries than 7zip too, which resisted enabling basic exploit mitigations like DEP and ASLR until 2018 and still doesn't enable the more advanced MSVC mitigations as far as I'm aware. There's no excuse for that in an application that's expected to handle untrusted files.
