Save content to a file in Chrome extension

Question

Is there any way to save a content like a string or an image to a file(like "C:\temp") in Chrome extension?
Does chrome or js provide any API to handle file system?

Do explicitly need to interact with the OS file system or do you just need a place to store your data like local storage? — Quintin Robinson, Mar 26 '13 at 02:47
I wanna interact with the OS file system, not chrome local storage. — Leslie Wu, Mar 26 '13 at 04:27

There is a way to trigger a system file save dialogue via JS.

function exportToFile() {
    var myString = "Lorem ipsum.";

    window.open('data:text/csv;charset=utf-8,' + escape(myString));
}
exportToFile();

Another way is to use the new FILE API.

BTW, if you want to download a lot of existing files, you might want to just generate a set of URLs and use a download manager to save them. – Tom May 19 '14 at 11:37
There is also `chrome.downloads` API. – Xan May 19 '14 at 11:40

No, there is no way for a chrome extension to manage the filesystem aside from using a custom NPAPI plugin con can get more info about using NPAPI plugin at http://developer.chrome.com/extensions/npapi.html
