How can I evaluate the best choice of archive format for compressing files?
I've just downloaded phpBB3 and saw they offer a bz2 (1.51 MB) and a zip (2.35 MB) download. This is the reason why I want to know if the ZIP file format has any advantages over bzip2.
According to the Wikipedia article, the zip-files can be compressed using the bzip2-compression algorithm. Why is the zip-file then that much bigger?
+1 "Can" doesn't mean "always will be": And in this case, that would be counter-productive, since the zip file only exists for the benefit of people without bzip decompression software. – Thilo – 2011-08-31T10:12:51.883

.zip
files with compression other thanDEFLATE
are not universial. – Jens Mühlenhoff – 2011-08-31T10:20:26.257
