TagSpaces:免费开源个人数据管理工具是一个优秀的个人数据存储管理的工具，支持本地网页、图片、PDF文件等文件的管理和浏览，方便用户存储、搜索查找资料;同时还提供各种浏览器的扩展插件，方便用户收集互联网中的各种格式的资料。

TagSpaces可以帮助用户用web2.0的tag方式来管理本地文件，用tag组织本地文件的软件本来就不多，而且很多并不好用，但TagSpaces却能让人眼前一亮。直接使用的是本地文件的本身的目录结构来管理。开始选定一个起始文件夹比如“资料”，下面的目录是“动物”“动漫”之类的;配合Mozilla Archive Format或者unmht扩展，可以极其方便地快速打开、切换MAFF或者mht，html等网页文件。样就不用再资源管理器和firefox直接频繁切换了，而且打开文件速度极快。

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.

TagSpaces offers you a convenient web interface to your local file system. It is implemented in JavaScript and HTML5, which are the technologies behind most of the modern web applications.
