《多媒體通信技術基礎》：
　　然而事情如果僅僅到此為止，那麼這也不過是菲利普·卡茲為私人恩怨而快意恩仇的行為，未必能得到後人的真正尊重。不過他做齣瞭一個讓所有計算機用戶都收益無窮的舉動，那就是宣布開放ZIP格式，任何人都可以自由使用ZIP編碼算法而不需要繳納任何費用。這個決定終改變瞭壓縮的世界，使得通用數據無損壓縮領域再無法齣現壟斷的商業巨鰐，真正意義上幫助瞭每個需要壓縮的計算機用戶。憑藉這個無私的行為，菲利普·卡茲真正成為他想成為的英雄。
　　2000年4月14日，年儀37歲的菲利普·卡茲被人發現倒斃在美國威斯康星州密爾沃基的一傢汽車旅館裏，據說死因是慢性酒精中毒引起的並發癥。這位天纔程序員從未在ZIP身上得到半點好處，堅持信念的結果是潦倒的生活。他為世界貢獻瞭一個的免費軟件，更為重要的是他締造瞭一種大眾化的壓縮格式，然而他卻過早的離開瞭這個世界。
　　During the process of multimedia municatiodevelopment； some things really deserve us to member.The borprocess of ZIP data pressiois one of them.
　　The victory of a rebel—The borof ZIP
　　Whepeople were using DOS operating system， the puter storage space is very limited.At the time， people desired to death to have aefficient data pressiosoftware to use.For example， i1984， one of the standard ponents of a personal puter is a 5.25inch floppy disk with 360kB capacity to save data.Each floppy disk cost money.If one caget the data pressed to several times smaller before the storage， one caabsolutely save quite a bit money.
　　For this reason， data pressiosoftware was highly desired.SEA developed the first ARC pressiosoftware using LZW algorithm under the MS—DOS environment.It was the predominate software under the MS—DOS environment.Technical speaking， ARC is a good software.But since it used patent algorithm， it is also a standard business software that charges whoever uses it.At the time， not many people who loves puter could afford it.At that time， most the puter lovers don't have that much money for something like floppy disks.But they love the puters.They have to think hard to find the way to get what they need and cost less.It is this hard thinking pushed the puter technology developed.The personal puter could be treated as a rebel pared with the maiframes since the first day it was appeared.It's one of the reasons for personal puters developed quickly and shortly after became a pioneer.At this time， one young software developer， Phillip W.Katz dropped iand tried to change pressioworld.
