message: Should mention the 1.93a beta, which was released in October 1991, about a year before 2.04g came out, and was the only way people could compress using "deflate" before the official 2.0 release.  The release of deflate seems to have given ZIP the final momentum to become the prevailing MS-DOS compression format (before that time there were a number of competitors)...

message: ZIP archives were once considered ubiquitous, but gradually have lost the meaning and have been largely replaced by other types of archive. That early popularity was result of tight code optimization, faster execution than any competing product and on average smaller archive. But what helped ZIP to the top, eventually brought it down. The shrinking user base was mainly result of losing performance, such as processing speed, inability to utilize or utilize efficiently other resources such as non-Intel CPUs, additional CPU cores, inability to produce spanned archives on HDD etc. For example PKZIP and later WinZip was eventually allowed creation of spanned archives on hard disk, however this was long after competing products did so. In practical terms this meant entire archive distributed over possibly dozens of slow media had to be created from scratch even if there was single problem with just one of them. Clearly main problem is unacceptable time involved to create archive as any removable media is slower than hard disc (Floppy, CDs etc.). Other archivers such as ARJ etc. allowed making entire archive of spanned volumes on hard disk which is faster and more reliable. Then each volume could be copied to one media disc at a time. Failure of one disc would simply mean need to copy just that one disc instead of making entire new archive disc by disc.
This entire paragraph needs work.  I've removed it, and will work on it when I get the chance, it's garbled to the max, dude.   a_man_alone (talk) 10:51, 19 December 2011 (UTC)
