    Nowadays it matters if you use a compression algorithm that can utilize multiple cores for packing/unpacking larger data. For a multiple GB archive that can be the difference between “I’ll grab a coffee until this is ready” or “I’ll go for lunch and hope it is done when I come back”

        I personally prefer bzip2 - but it needs to be packed with pbzip, not the regular bzip to generate archives that can be extracted on multiple cores. Not a good option if you have to think about Windows users, though.

          Ah I have to use Windows for work and that’s the source of most of my compression needs. Thanks for the info though, I’ll look into this

      Because gzip and bz2 exists. 7z is almost always a plugin or addon, or extra application. While the first two work out of the box pretty much everywhere. It also depends on frequency of access, frequency of addendum, size, type of data, etc. If you have an archive that you have to add new files frequently, 7z is gonna start grating on you with the compression times. But it is Ok if you are going to extract very frequently from an archive that will never change. While gz and bz2 are overall the “good enough at every use case” format.

          Windows having tar.gz support is great.

          I have scripts for generating log bundles on user computers and sending to a share. tar.gz is great for compressing ~2.5GB text to send over VPN, and then I can open the .tar.gz direct from the network drive with minimal additional delay opening a 500MB text file inside.

      For archiving/backupping *NIX files, tar.whatever still wins as it preserves permissions while 7z, zip and rar don’t

      Oh, and while 7z is FOSS and supported out of the box on most Linux desktop OSes and on macOS, Windows users will complain they need to install stuff to open your zip. Somehow, tar.gz is supported out of the box on Linux, macOS, and yes Windows 10 and 11!

    Now we have so much bandwidth it doesn’t matter

    Squints eyes

    Now we just don’t care about even the slightest modicum of efficiency

    In the early days of the internet, WinZip was a must have tool. My college had a fast internet connection. I say fast but I bet it was less than 1Mb shared between everyone. Way faster than the 33k modem I had at home.

    I used my college connection to download so much and then took it home on floppy disks. For files larger than 1MB I’d use WinZip to split files up.

      And then you get it all off the floppy’s only to realize 10% of it is corrupted

          And that’s when you learned about parity files…

          When par2 came out that was huge for me. Didn’t use floppies anymore, but the ability to only download the required amount of parity blocks was great.

    How about when peoples websites would put the sizes of linked images and files so you could estimate how long it would take to download a given image and such? Basically anything 30KB and above would have a size warning attached.

    still using 7z. less space, and easier to browse, since the operating system doesnt have to deal with all the files, easier for the cloud to tag. not caring about space makes the storage more expensive, even games are bigger now with little to none content.

      Depends on what you’re doing. Dumps of multitrack CD media should always be bin+cue or a compressed version thereof, such as chd. DVDs and Blu-rays can dump as iso. There are also some extremely niche cases such as specific copy protection that require mdf+mds for a proper dump, but that won’t be something the average user ever encounters. Basically, those formats exist and are still used for a reason, whether you understand them or not.

      I do reserve some hatred for people who dump PS1 games as iso, or who use ccd+img+sub for things where the subchannels have no valid usage.

      1:1 copies of the bits on the disc is a valid option that some people prefer. Especially if you want to make your own physical disc or make compressed files encoded in a very specific way. It’s also the most reliable way to archive a disc for long-term storage.
