    About this document

    This document was last updated on March 2, 2012 and follows the W3C Specifications (Working Draft) drafted on April 19, 2011.
    The draft is no more actively maintained, the specification is abandonned for the moment as it didn't get any significant traction.

    Basic concepts

    You request access to a sandboxed file system by calling window.requestFileSystem(). CallingrequestFileSystem()creates new storage for your web app.The argument of the a successful callback is the FileSystem object, which has two properties: the name and root of the file system.

    The FileSystem object is your gateway to the entire API and you will use it a lot. So once you have a reference, cache the object in a global variable or class property.

    Attributes
