AWS S3 SDK Get the folder instead of a file

Question

Below codes can get 1 single file from AWS 3 but, what about a folder?

var _key:int=Account.lessons[dl_i].id;
var dest:String =  Conf.Dir+_key;
var request:G

The javascript code below will count the files inside a "folder"; in fact, it will list objects sharing the same part of the name, as @Viccari pointed out there is no folder. As data.Contents will be an array containing details on "the files inside the folder", you would then "get the folder".

var bucket  = 'the_bucket_name';
var path_to_folder = 'path/to/the/folder/';
var params= {Bucket: bucket, Delimiter: path_to_folder };
s3.listObjects(params, function (err, data) {
    if (err) {
      console.log('Could not load objects from S3', err);
    } else {
        console.log('Loaded ' + data.Contents.length + ' items from S3');
    }
});

There is no such stuff as folders in Amazon S3. It is a "flat" file system. The closer you can get to folders is adding prefixes like foo/bar/filename.txt to your file names. Even though several S3 tools will show you stuff as if they were contained inside folders, this concept does not exist on S3.
