Will IE9 support the HTML5 File API?

Will IE9开发者_如何学运维 support the HTML5 File API?

It doesn't really look like it: I can't see anything in the Internet Explorer 9 Beta Guide for Developers. True, it's not the final release yet, but you'd expect to see something about it in the Beta version if they were going to support it....

caniuse.com says "support unknown".

Internet Explorer 9 (final) does not support the File API, but does support the Drag and Drop API.

Microsoft's "HTML5 Labs" incubator is working on File API support and it is assumed that it will be in IE 10 most likely.

IE10 starts supporting File API. http://msdn.microsoft.com/en-us/library/ie/hh673539%28v=vs.85%29.aspx
