access user arbitrary folders with chrome localstorage API

Question

I'm developing an app on Google chrome which could be able to read and write files to arbitrary folders on the user’s hard drive, such as their My Pictures or My Documents folder.

I want my app to has its one folder, like "Users/Username/App", so users could be able to access some of the data, created and edited by the app. How can I do this?

I read the book "Using the HTML5 Filesystem API", so I know it's actually not possible with HTML5 Filesystem API alone. Same thing was possible by opera 11, 12. (see: http://dev.opera.com/articles/view/file-i-o-api-for-widgets/). Chorome mediaGalleries API do same things but just for media file but I want to use html, xml and office files

Answer 1

It doesn't sound like you've looked at the list of Chrome App APIs. Have you? Among them is the fileSystem API, which is evolving quickly to include directory access.
