[5 minut čtení] Kompresní formát ZIP je přes třicet let starý, přesto by mohl být i v současnosti pro někoho zajímavý. Podporuje několik kompresních algoritmů a ty si zde postupně rozebereme. V tomto díle se budeme věnovat hlavně Shrink/LZW. ZIP je a hlavně byl velmi rozšířený a populární program pro archivaci a kompresi dat. První program PKZIP vznikl již v roce 1989. V současnosti v Linuxu a jiných Unixech použijete patrně open source Info-ZIP ( zip a unzip) a ve Windows například WinZip, 7-Zip nebo třeba PeaZip. Poslední dva najdete i v Linuxu (nedávno se objevila oficiální linuxová verze 7-Zip).
