Phonegap File transfer errors

I'm trying to get my PhoneGap app to create a directory on the mobile device, but i keep running into the same errors, which are a mixture of:

ENCODING_ERR - 5 - The URL is malformed. Make sure that the URL is complete and valid.

PATH_EXISTS_ERR - 12 - The file or directory with the same path already exists.

INVALID_MODIFICATION_ERR - 9 - The modification requested is not allowed. For example, the app might be trying to move a directory into its own child or moving a file into its parent directory without changing its name.

$( document ).on( 'click', '#A2', function () {
    downloadPhoto();
} );

function downloadPhoto() {
        alert( "Downloading" );
        window.requestFileSystem( LocalFileSystem.PERSISTENT, 0, function systemSuccess( dirEntry ) {
            alert( "Download about to begin" );
            dirEntry.root.getDirectory( 'thisfilenamewillneverexist', { create: true }, function ( fileSystem  ) {
                alert( fileSystem );
            }, errorHandler );
        }, errorHandler );
    }

function errorHandler( e ) {
    var msg = '';
    switch ( e.code ) {
        case FileError.ENCODING_ERR:
            msg = 'ENCODING_ERR';
            break;
        case FileError.INVALID_MODIFICATION_ERR:
            msg = 'INVALID_MODIFICATION_ERR';
            break;
        case FileError.INVALID_STATE_ERR:
            msg = 'INVALID_STATE_ERR';
            break;
        case FileError.NO_MODIFICATION_ALLOWED_ERR:
            msg = 'NO_MODIFICATION_ALLOWED_ERR';
            break;
        case FileError.NOT_FOUND_ERR:
            msg = 'NOT_FOUND_ERR';
            break;
        case FileError.NOT_READABLE_ERR:
            msg = 'NOT_READABLE_ERR';
            break;
        case FileError.PATH_EXISTS_ERR:
            msg = 'PATH_EXISTS_ERR';
            break;
        case FileError.QUOTA_EXCEEDED_ERR:
            msg = 'QUOTA_EXCEEDED_ERR';
            break;
        case FileError.SECURITY_ERR:
            msg = 'SECURITY_ERR';
            break;
        case FileError.TYPE_MISMATCH_ERR:
            msg = 'TYPE_MISMATCH_ERR';
            break;
        default:
            msg = 'Unknown Error';
            break;
    };
    alert( 'Error: ' + msg );
}

Why or how does that file name already exist if its the first time I'm creating it?

In successcallback of requestFileSystem you will be passed a "fileSystem" parameter which in simple terms is the mother (main Object/Parent) of File API.

If you do "fileSystem.root.getDirectory" in the successcallback you will be passed a parameter of "directoryEntry" which basically is the same of "fileSystem.root" therefore you can access all the methods listed under directoryEntry right away and don't need to use the root.

Managed to fix the error, turns out you dont need to include "root" when creating a file in a newly created directory.

Code for anyone else stuck on this problem or something similar:

var folderDir;
var fileDir;
var FolderName = "OSMaps";

$( document ).on( 'click', '#A2', function () {
    window.requestFileSystem( LocalFileSystem.PERSISTENT, 0, downloadPhoto, errorHandler);
} );

function downloadPhoto(fileSystem) {
    fileSystem.root.getDirectory( FolderName, { create: true, exclusive: false }, 
    function ( dirEntry ) {
        folderDir = dirEntry;
->      folderDir.getFile( 'test.jpg', { create: true, exclusive: false }, <-
        function ( fileEntry ) {
                fileDir = fileEntry;
        }, errorHandler );
}, errorHandler );
