if you could pick a standard format for a purpose what would it be and why?

e.g. flac for lossless audio because…

(yes you can add new categories)

summary:

  1. photos .jxl
  2. open domain image data .exr
  3. videos .av1
  4. lossless audio .flac
  5. lossy audio .opus
  6. subtitles srt/ass
  7. fonts .otf
  8. container mkv (doesnt contain .jxl)
  9. plain text utf-8 (many also say markup but disagree on the implementation)
  10. documents .odt
  11. archive files (this one is causing a bloodbath so i picked randomly) .tar.zst
  12. configuration files toml
  13. typesetting typst
  14. interchange format .ora
  15. models .gltf / .glb
  16. daw session files .dawproject
  17. otdr measurement results .xml

    zip or 7z for compressed archives. I hate that for some reason rar has become the defacto standard for piracy. It’s just so bad.

    The other day I saw a tar.gz containing a multipart-rar which contained an iso which contained a compressed bin file with an exe to decompress it. Soooo unnecessary.

    Edit: And the decompressed game of course has all of its compressed assets in renamed zip files.

      It was originally rar because it’s so easy to separate into multiple files. Now you can do that in other formats, but the legacy has stuck.

      .tar.zstd all the way IMO. I’ve almost entirely switched to archiving with zstd, it’s a fantastic format.

          Gzip is slower and outputs larger compression ratio. Zstandard, on the other hand, is terribly faster than any of the existing standards in means of compression speed, this is its killer feature. Also, it provides a bit better compression ratio than gzip citation_needed.

            Yes, all compression levels of gzip have some zstd compression level that is both faster and better in compression ratio.

            Additionally, the highest compression levels of zstd are comparable in compression level to LZMA while also being slightly faster in compression and many many times faster in decompression

          gzip is very slow compared to zstd for similar levels of compression.

          The zstd algorithm is a project by the same author as lz4. lz4 was designed for decompression speed, zstd was designed to balance resource utilization, speed and compression ratio and it does a fantastic job of it.

        The only annoying thing is that the extension for zstd compression is zst (no d). Tar does not recognize a zstd extension, only zst is automatically recognized and decompressed. Come on!

          If we’re being entirely honest just about everything in the zstd ecosystem needs some basic UX love. Working with .tar.zst files in any GUI is an exercise in frustration as well.

          I think they recently implemented support for chunked decoding so reading files inside a zstd archive (like, say, seeking to read inside tar files) should start to improve sooner or later but some of the niceties we expect from compressed archives aren’t entirely there yet.

          Fantastic compression though!

            Not sure what that does.

            Yes, you can use options to specify exactly what you want. But it should recognize .zstd as zstandard compression instead of going “I don’t know what this compression is”. I don’t want to have to specify the obvious extension just because I typed zstd instead of zst when creating the file.
