DeviceStorage interface is used to access files on a specific storage area available on the device. A storage area is, in essence, a file system repository even if it hides the reality of the underlying file system.
To access a storage area, you must use the
navigator.getDeviceStorage() method, which returns
DeviceStorage objects. You then use those objects' methods and properties to access the content of the storage area.
- A Boolean value that indicates if this storage area is the default destination for storing new files (
