html - Modifying Local Files Using HTML5 and JavaScript

Question

Is there any way I can use HTML5 and JavaScript to modify a file on my system? I'm OK with running Chrome or Firefox with specific options or opening permissions in some other way.

Ideally I would like test this by having my browser rename a file on my desktop.

Answer 1

Yes, you can do this, this link details some of the available functionality:

Just remember, it's not supported in the major browsers yet, and it's likely when it is many of your visitors will not upgrade for quite some time.
