oke the user, for example by
installing a Chrome extension. The relevant Chrome API can be found [ here

##  Basic concepts

There are two ways to get access to a ` FileSystem ` object:

  1. You can directly ask for one representing a sandboxed file system created just for your web app directly by calling ` window.requestFileSystem() ` . If that call is successful, it executes a callback handler, which receives as a parameter a ` FileSystem ` object describing the file system. 
  2. You can get it from a file system entry object, through its [ ` filesystem ` ](/en-US/docs/Web/API/FileSystemEntry/filesystem "filesystem") property. 

##  Instance properties

[ ` FileSystem.name ` ](/en-US/docs/Web/API/FileSystem/name) Read only

    

A string representing the file system's name. This name is unique among the
entire list of exposed file systems.

[ ` FileSystem.root ` ](/en-US/docs/Web/API/FileSystem/root) Read only

    

A [ ` FileSystemDirectoryEntry ` ](/en-
US/docs/Web/API/FileSystemDirectoryEntry) object which represents the file
system's root directory. Through this object, you can gain access to all files
and directories in the file system.
