The original standard for .zip archives was established by Phil Katz's company PKWARE and its PKZIP product. This product was shareware but was never open-sourced, but the archive format was published. This publication produced the Info-Zip open-source project at U.C.L.A. and this project delivered the zip and unzip commands. These commands -- and they are commands, not mousey-clicky icons -- run on almost all systems: MS-DOS/PC-DOS, Win16/Win32/Win64, OS/2 (16-bit & 32-bit), MacOS, Linux, FreeBSD, OpenBSD, NetBSD, Solaris/SunOS, AIX, HP-UX and a whole bunch of others. Most UNIX-like systems bundle Info-Zip these days, as it is open source and freely distributable. PKZIP dates to about 1982. Info-Zip dates to about 1991. The standard for the archive is that published by PKWARE. The standard for the unzip command is that for Info-Zip.
