Titanium - How to list all your files/folders from your SD Card

filesystem.js

var mkdfs = require("dk.mikkendigital.mkdfs"); // <- this module allows you to acess the SD Card root, without the AppDirectory

exports.showFileSystem = function(){
    
    //Window that will be pop-up with a tableview
    var win = Ti.UI.createWindow({
        height:'100%',
        width:'100%',
    });
    
    //I forgot, but first test if externalStorage exists ok?
    
    var dir = Titanium.Filesystem.getFile(Titanium.Filesystem.externalStorageDirectory);
    var directoryStr = dir.getParent().getDirectoryListing();
    var directoryArr = directoryStr.toString().split(',');
    var dirData = [];

    for (var i=0; i<directoryArr.length; i++) {
        Titanium.API.info(directoryArr[i]);
        var row = Ti.UI.createTableViewRow({
            title: directoryArr[i],
            value: 'file://'+mkdfs.externalStorageDirectory + Titanium.Filesystem.separator,
        });
        dirData.push(row);
    };

    var tableDirs = Ti.UI.createTableView({
        height:'100%',
        width:'100%',       
    });
    
    tableDirs.addEventListener('click', function(e){
        var newRows = [];
        var secDir = Titanium.Filesystem.getFile(e.rowData.value + e.rowData.title);
        
        //Test if secDir is a File or really a Directory        
        if(secDir.isFile()){
            Ti.API.info( secDir.nativePath + ' ' + secDir.name);
            //Do anything with the file, like call a function..
            return;
        }
        
        var secDirStr = secDir.getDirectoryListing();
        for (i=0, max=secDirStr.length; i<max; i++){
            var row = Ti.UI.createTableViewRow({

            newRows.push(row);
        }
        tableDirs.setData([]);
        tableDirs.setData(newRows); 
    });
    
    tableDirs.setData(dirData); 
    win.add(tableDirs);
    win.open();
