How to access the file system in chrome os

Question

Is it possible to have an extension read/write to/from the local file system in chrome os?

Thanks in advance?

Solution 1

Yes - you can read/write with the File API: http://www.html5rocks.com/en/tutorials/file/filesystem/

and you can even hook up your extension to the file system. I've wrote about it: http://greenido.wordpress.com/2011/06/02/chrome-apps-web-store-and-the-new-chromeos-file-api/

It sounds like you want to access the root parent directory. In order to do that you'll have to put your chromebook into developer mode, and when signing in enable debugging options. That will give you the option to view and edit chromeos system files. Just be careful and make sure you create a recovery disc first.
