I'm playing around a bit with the FileSystem API.

I've found a lot of examples where you generate a download link and let the user download the file the browser way.

I would like to know two things:

1. Is there any way to write the ajax result in the fiddle as a file directly to the disk (without any type of prompt). Like to the user's desktop for example.




2. Is blob the most suitable format for this?

http://jsfiddle.net/FBGDe/

var xhr = new XMLHttpRequest();

xhr.onreadystatechange = function(){

    if (this.readyState == 4 && this.status == 200){

        console.log(this.response, typeof this.response);

        var img = document.getElementById('img');

        var url = window.URL = window.webkitURL;

        img.src = url.createObjectURL(this.response);

    }

}

xhr.open('GET', 'http://www.newyorker.com/online/blogs/photobooth

                                                       /NASAEarth-01.jpg');

xhr.responseType = 'blob';

xhr.send();
