我正在通过W3C规范提案,
从这里可以看到：http://www.w3.org/TR/file-system-api/
“Work on this document has been discontinued and it should not be
referenced or used as a basis for implementation.”
FileAPI不再是HTML5规范,还是意味着它的实现细节只会改变？
解决方法
File API本身不仅没有死机,而且还是reasonably well-supported.(IE8是唯一重要的[和快乐后退]桌面浏览器,无需支持.)
目录和系统文件…
…defines an API to navigate file system hierarchies,and defines a means by which a user agent may expose sandBoxed sections of a user’s local filesystem to web applications. It builds on File API,which in turn built on File API: Writer,each adding a different kind of functionality.
显然有问题,所以努力被放弃,可能有利于做别的事情.
…I can’t seem to grasp how can browsers implement a feature and then suddenly realise they no longer want to support it
你可能会发现this thread有趣.基本上只有Chrome才有了. Mozilla,Apple和Microsoft(和其他人)不想实现它.例如：Google决定不再需要它,但是他们从不说服其他供应商是值得实施的.仅由一个供应商实施的Web标准不是Web标准.最后的指甲是announced here.
