I have always thought that the 7-Zip format is interesting in the way it (or the reference implementation of the compressor, at least) groups files by extension, which I guess helps compression by making it more likely that chunks of files that are common within a filetype end up in the dictionary before it fills up with chunks from all filetypes. Do you have any thoughts about this? Have you looked at the 7-Zip format?

- alphapapa 10y agoThat's cool, thanks for sharing. I actually meant to ask the OP if they had looked at the 7-Zip format when designing their own archive format, but maybe they don't need to...
