WinRAR vs Zip vs 7zip vs Others

[alephz]

Last time I read about problems with large 7z SFX archive (> 100 Gb) on russian site (CyberForum.ru). Problem was intensively tested (600 Gb free on HDD, 28 Gb RAM) - SFX-archive each time was broken for large files. Relatively small archives (up to 30 Gb on some computer was OK). But I'm personally seen as 7z create broken ordinal archives on medium size files (~400 Mb) if allowed memory was very low. I think this is just a BUG - no ErrCode returned or checked inside COM-chain calls or smth like.

Also, no matter if a few bits flipped due disk or transmission error - with Rar ECC procedure it just a few extra clicks to recover damaged data, but 7z archive dead.
