[Aravindba]

Hi, I am developing ios app, in that need to create folder on ios device, i am using following code to create folder named "FT2019" ,is it my code is correct ? if correct then how see that folder on ios device physically.

if (device.platform.toLowerCase() == "android") {
window.resolveLocalFileSystemURL(cordova.file.externalRootDirectory, onFileSystemSuccess, onError);
} else {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, onError);
}

function onFileSystemSuccess(fileSystem) {
var entry = "";
if (device.platform.toLowerCase() == "android") {
entry = fileSystem;
} else {
entry = fileSystem.root;
}
entry.getDirectory("FT2019", {
create: true,
exclusive: false
}, onGetDirectorySuccess, onGetDirectoryFail);
};

    function onError(e) {
        alert("Fail to get folder");
    };




    function onGetDirectorySuccess(dir) {
        dummyFilePath = dir.toURL();
    };


    function onGetDirectoryFail(dir) {
        alert("Fail to get folder");
    };
