How to get filesNames as it was in selected folder structure in indesign javascript?

var filesB =[];
var myfile=Folder.selectDialog();
var fileList =myfile.getFiles(); 
filesB =  fileList.sort(sortStringByPaddingNumbers);
for (i = 0; i < filesB.length; i++) { 
    $.writeln(filesB[i]);
 }

/**

 * leading zeros to all numbers

 *  {String} a - a string to order.

 */
function sortStringByPaddingNumbers(a, b) {
    c = String(a.name);
    d=  String(b.name);
    var aParts = c.split(/(\d+)/),
        bParts = d.split(/(\d+)/),
        len = Math.max(aParts.length, bParts.length);
    for (var i = 0; i < len; i++) {
        if (aParts[i].length === bParts[i].length)
            continue;
        var an = Number(aParts[i]),
            bn = Number(bParts[i]);
        if (an === an)
            aParts[i] = ('0000000000' + aParts[i]).slice(-10);
        if (bn === bn)
            bParts[i] = ('0000000000' + bParts[i]).slice(-10);

Hey, very well done on fixing it! For information, here is my preferred way below. Also note I made a mistake on the sorter function: please change Math.max to Math.min. This will throw error in some cases.

- Mark

var myfile = Folder.selectDialog();
if (myfile) {
    var fileList = myfile.getFiles();
    fileList.sort(function (a, b) { return sortStringByPaddingNumbers(a.displayName, b.displayName) });
    for (i = 0; i < fileList.length; i++)
        $.writeln(fileList[i].displayName);
}

function sortStringByPaddingNumbers(a, b) {
