I have a Node Webkit Desktop App and need to download files from the server and save locally for when users are offline. I can download and save a file when I know what the file name is, but how do I read the contents of a directory on the server so I can download each file?

```
function cacheFiles(filelink, filepath, cb) {
    var path_array =  filelink.split("/");
    var foldername =  path_array[path_array.length - 2]

//create new folder for locally html files
var newdir = filepath + '/' + foldername;
if (fs.existsSync(newdir)){
    alert('file already exists, cannot cache this file.');
} else {
    fs.mkdirSync(newdir);
}
//download and save index.html - THIS WORKS
var indexfile = fs.createWriteStream(newdir+'/index.html');
var request = http.get(filelink, function(response) {
    response.pipe(indexfile);
    indexfile.on('finish', function() {
        indexfile.close(cb);
    });
});
//read contents of data folder - THIS DOESN'T WORK
var datafolder = filelink.replace('index.html','');

fs.readdir( datafolder, function (err, datafiles) { 
    if (!err) {
        console.log(datafiles);
    }else{
        console.log(err) ; 
    }   
});

```

}

The error I get in my console is: 

> 
> "ENOENT: no such file or directory, scandir
>  'C:\Users\my.name\desktopApp\app\http:\www.mysite.co.uk\wp-content\uploads\wifi\_corp2\data'"
> 
> 
> 

The above is looking for the files locally and not at the online link I supplied in ***filelink*** eg. 
<http://www.mysite.co.uk/wp-content/uploads/wifi_corp2/data>
