FileSystem
The File and Directory Entries API interface FileSystem
is used to represent a file system. These objects can be obtained from the filesystem
property on any file system entry. Some browsers offer additional APIs to create and manage file systems, such as Chrome's requestFileSystem()
method.
This interface will not grant you access to the users' filesystem. Instead, you will have a "virtual drive" within the browser sandbox if you want to gain access to the users' file system, you need to invoke 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:
- 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 aFileSystem
object describing the file system. - You can get it from a file system entry object, through its
filesystem
property.
