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.
