Determines the location of the file or folders to be selected.
StorageTarget requires a StorageTarget enum assignment.
Use application-specific isolated storage. No restrictions are applied to folders, so be aware that shared content will be displayed as well, unless an explicit file extension restriction is applied.
Use external (SD card) storage.
