TagSpaces:免費開源個人數據管理工具是一個優秀的個人數據存儲管理的工具，支持本地網頁、圖片、PDF文件等文件的管理和瀏覽，方便用戶存儲、搜索查找資料;同時還提供各種瀏覽器的擴展插件，方便用戶收集互聯網中的各種格式的資料。

TagSpaces可以幫助用戶用web2.0的tag方式來管理本地文件，用tag組織本地文件的軟件本來就不多，而且很多並不好用，但TagSpaces卻能讓人眼前一亮。直接使用的是本地文件的本身的目錄結構來管理。開始選定一個起始文件夾比如“資料”，下面的目錄是“動物”“動漫”之類的;配合Mozilla Archive Format或者unmht擴展，可以極其方便地快速打開、切換MAFF或者mht，html等網頁文件。樣就不用再資源管理器和firefox直接頻繁切換了，而且打開文件速度極快。

TagSpaces is open sourced and published under theAGPL license. It is designed to be easily extended with different plugins for visualization of directory structures or for opening of different file types.

TagSpaces is running completely offline on your computer, smartphone or tablet and does not require internet connection or online registration. You can still use platforms like ownCloud, Dropbox orBittorrent Sync in order to sync your files between devices.
