FileSystemSync

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

In the File System API, a FileSystemSync object represents a file system. It has two properties.

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.

Basic concepts

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.
