Solid block size

Positive Comment by SagePtr

Can specify solid block size for compression. This feature is missing in WinRAR, which can create only fully solid or non-solid archives.
It's very useful when you need to pack many small files into single archive with good compression rate (which cannot be done without making archive solid in case of lot small files), but retain ability to quickly extract arbitary file. In this mode, files are grouped into blocks of given size, so you don't need to skip entire archive to get the file in the end, you just need to skip from beginning of the file's block.

No recovery/parity. There needs to be improvements for long term archiving.

Some random stuff...

Comment by realnabarl

The most popular formats are zip, rar and 7z.

Zip is free, but its features are quite limited nowadays.

Rar has quite a lot nice features.

7z does not have recovery record feature, but that is not very important, for my experience these years, I'm not helped with WinRAR recovery record feature. Internet transfer corruption? I did not experienced that.

The compression ratio is not that important like earlier days. So Rar cannot be called "bad" in most cases. The most superior of 7z is lossless bitmat compression (like BMP).

Do we need other formats?
There are arc format from Small FreeArc iconFreeArc, b1 format from Small B1 Free Archiver iconB1 Free Archiver, kz from Small KuaiZip iconKuaiZip, PEA from Small PeaZip iconPeaZip, if there are more good format, please comment. Arc is better IMO, and it is still in developing. But all of these do not have big difference, and the newer ones do not supported by most archivers. Self-extract archive with exe? Not a bad idea but is it really necessary for us to do that? It will confuses people IMO. So maybe we still just need 7z.
