    Hello.

    Is it me or does mac OS Big Sur v11.4's Archive Utility app cannot
    extract *.7z files correctly?

    I got a huge 141 MB 7z file (can't share it to the public) with a WAV
    file inside. It was extracted without errors, but none of the players
    (Windows' and third parties too) could play this 250 MB WAV file after extracting it. I tried The Unarchiver app to extract the same 7z file's
    WAV file and play it. No problems. What the heck?

    According to file command, it says "... 7-zip archive data, version
    0.4". Does Big Sur v11.4's Archive Utility app have issues with *.7z
    files? :/

    Thank you for reading and hopefully answering soon. :)

    Why would you think that 7z files can be extracted by the mac's archive utility?

    I got a huge 141 MB 7z

    Again, why would you think it would work? 8z is a relatively minor niche
    format for archives, and there are tools to uncompress 7z files,
    including The Unarchiver and p7zip (available via homebrew) as well as
    direct download from 7-zip.

    <https://www.7-zip.org/download.html>

    I've had The Unarchiver installed for years and it is the default
    application for opening archives on my system.

    It´s not just you. Big Surs extractor is broken. It never worked with big archives.
    I use ditto to compress big (several GB) database files as PKzip archives. BigSur could never extract them correctly.
    I use the Unarchiver, that works fine.

    I was able to reproduce this by making my own 7z file from a WAV file
    that I converted from a MP3 with Audacity. I uploaded it to http://zimage.com/~ant/temp/MP3toWAVsample.7z (38.3 MB). Please try
    extracting with mac OS Big Sur v11.4's Archive Utility app and playing

    Archive Utility can indeed can extract most 7z files. I've done it

    worked fine.

    I suspect something is different about the way the archive Ant is having trouble with was created

    I just right click on the file in Windows Explorer and its defaults with

    Ah OK. I was surprised to see Apple added support for *.7z file format
    since it never had a third party archive program in this clean Big Sur installation from the end of 2020. Also, it was a first time I had to
    open one in this Mac.

    https://anderegg.ca/2020/08/14/what-file-types-does-apples-archive-utility-open was an interesting read.
    https://fileinfo.com/software/apple/archive_utility doesn't even mention
    .7z.

    Archive Utility can indeed can extract most 7z files.

    It fails to do it often enough that it's not worth it.

    I've done it frequently, and just tested it out on an old MS DOS
    6.22.7z archive. It worked fine.

    And when it fails, it doesn’t even tell you it failed, so you have
    useless files that were expanded. And if you don't check them right
    away, assuming that no error means everything is good, then you can
    easily end up with useless files and not archive.

    And support for 8z at all is pretty recent, right? I know the Archive
    Utility didn't use to support 7z files at all. But then again, it also
    had issues with some zip files many years ago.

    I suspect something is different about the way the archive Ant is having trouble with was created

    Probably, but I think there is an issue with 7z and Archive Utility too.

    I've had The Unarchiver installed for years and it is the default
    application for opening archives on my system.

    Same, but it's not the default. I just use it as a backup for things

    I've done it frequently, and just tested it out on an old MS DOS
    6.22.7z archive. It worked fine.

    And when it fails, it doesn???t even tell you it failed, so you have
    useless files that were expanded. And if you don't check them right
    away, assuming that no error means everything is good, then you can
    easily end up with useless files and not archive.

    And support for 8z at all is pretty recent, right? I know the Archive
    Utility didn't use to support 7z files at all. But then again, it also
    had issues with some zip files many years ago.

    I never had problems with zip files. What issues were there?

    What did you use to create it? Are any specific options set in that app

    I just right click on the file in Windows Explorer and its defaults with
    the 64-bit 7-Zip program from https://www.7-zip.org. I tried add to
    archive manually with its options (https://justpaste.it/img/69bd8aa11a51f92afa0b0d57ded0a00d.gif). Both
    were in my over decade old, updated 64-bit W7 HPE SP1 PC.

    Ok, thanks.

    I uploaded it to http://zimage.com/~ant/temp/MP3toWAVsample.7z (38.3
    MB). Please try extracting with mac OS Big Sur v11.4's Archive Utility
    app and playing its WAV file.

    On both of these systems:
    * macOS 10.15.7 (Catalina)
    * macOS 11.2.3 (Big Sur)

    Archive Utility: archive gets extracted but is not a proper WAV file
    and cannot be played.

    The Unarchiver: archive gets correctly extracted and can be played.

    Thank you for reproducing it on your end. :) Wow, even Catalina. BTW,
    how come you're not on v11.4 for Big Sur?

    Inertia, mostly. : ) I have several Macs of various models here at home,
    and while some run Big Sir, others run Catalina, mostly because I
    haven't yet taken the time to verify that all of the stuff I have
    installed is fully compatible with Big Sur. As an example, one of the
    headless Mac minis in my server closet is still running Catalina because
    it runs several critical Docker containers that must continue running
    24/7 without issue, and I haven't had time to test them in Big Sur. I'll
    get around to it eventually - no rush.

    You're welcome. Just for kicks, I made 7zip compress the same WAV file
    into a zip file to retest. No problems even though bigger size.

    Hello.

    Is it me or does mac OS Big Sur v11.4's Archive Utility app cannot
    extract *.7z files correctly?

    Why would you think that 7z files can be extracted by the mac's
    archive utility?

    Archive Utility can indeed can extract most 7z files.

    It fails to do it often enough that it's not worth it.

    I've done it frequently, and just tested it out on an old MS DOS
    6.22.7z archive. It worked fine.

    It was many years ago and I don't remember, but I do remember having to
    use other tools to correctly extract some zip archives some time ago.
