壓縮軟體只是一種工具，平時不怎麼會使用到，有就可以了。而且現在計算機效能和網速讓大家對於檔案大小已經沒有這麼敏感了。所以投資人都不看好這個市場，就沒人出錢做啊。
不過，最近發現WinZip好像還是推了一款中文免費版本（http://www.

），還很低調，看上去現在想起來中國市場，但是不知道是不是為時已晚啊。
2樓：
作業系統自帶基本的壓縮、解壓，Windows Explorer 老早就可以直接瀏覽 zip 檔案，這對大多數人就已經夠用了。
至於分享檔案，除了 P2P，沒什麼場合是非打包不可的，無論你拿 QQ 郵件還是網盤。畢竟壓縮本身不是乙個最終的目的。
至於移動網際網路發展跟它們就更沒關係了。
當然這和計算機效能啊網速啊啥的完全沒關係。你知道摩爾定律的話，順便了解一下安迪比爾定律去啊。

這與「石油永遠採不完」的道理是一樣的，壓縮軟體的產生背景是昂貴的儲存、低速的傳輸，當目的需求日益不成問題時，它的再優化動力就不存在了。

根據題主的問題，我反問乙個問題，為啥膝上型電腦cpu更新沒有手機和平板電腦的更新換代快？
關鍵是市場需求，如果需求飽和，利潤飽和，誰還會去追逐更呢？
之前有人提問為啥麻辣燙的積聚在一起賣，同樣一定數量之後就不再增加了不是搞研究的，生活所需

為什麼近些年義大利西班牙希臘等國家經濟倒退，而德國卻穩步發展，除了歐債危機還有什麼具體原因
小斧頭 溫鐵軍教授提到歐債危機很大的乙個原因就是歐盟的建立讓各國貨幣統一，各國就沒有辦法通過增發或減少貨幣調整經濟。英國沒有收到很大衝擊就是因為他不用歐元用英鎊。第二就是德國成為歐盟經濟主導，德國的製造業已擊敗歐盟多國製造業。希臘原來是歐洲造船業大國，加入歐盟後造船業直接廢掉，現在基本不能生產出一條...
為什麼近些年日本人的平均身高降低了？

為什麼近些年的國產動畫沒有現實題材的作品？
呂薄冰 除了 理想禁區 還有點黑沈殘之外，大多數國漫是起點YY文改編的，除了種馬題材因政策因素不敢拍之外，其餘可以說無所不YY。你的問題相當於問 為什麼國漫缺少古谷實伊藤潤二這樣的人呢？以前以為，中國不缺畫師只缺創意，現在可以欣慰的是，創意不缺了，其實題材有的是，建議二次元圈的 改編獵頭 拓寬視野，...
