Should $cordovaFile.getFreeDiskSpace() return 0 in an emulator?

Hi,

I have this code running in a controller and the retuned free disk space is 0.
Is this correct or is there something wrong with the value

$ionicPlatform.ready(function() {
        $cordovaFile.getFreeDiskSpace()
        .then(function (success) {
            $scope.debugMessages.push({name:'success:'+success});
        }, function (error) {
            $scope.debugMessages.push({name:'error:'+error});
        });
});

The same code seems to fail when using the Ionic View APP and for now my safari debugger doesn’t connect to my phone. Not sure why

Thank you
