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 specification is abandonned for the moment, failing to get significant traction.

The FileSystemSync 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

Attribute Type Description
name readonly DOMString Name of the file system. The name must be unique across the list of exposed file systems.
root readonly DirectoryEntry The root directory of the file system.
