Cannot access the file created by my app
===

I have the following block of code in my program. It creates a folder and a simple csv file. The file can successfully be created, by using ASTRO, I am sure the file and folder are created, but when I connect the device to my desktop, I cannot find the folder nor the file, what can I do to make them accessible in my desktop? The device I am using is Galaxy Nexus.

    File folder = new File(Environment.getExternalStorageDirectory()+"/Chico");
	if(!folder.exists()){
		folder.mkdir();
	}
	final String record = folder.toString() + "/" + "record.csv";
	new Thread(){
		public void run(){
				try{
					FileWriter fw = new FileWriter(record);
					fw.append("ClientName");
					fw.append(',');
					fw.append("SiteName");
					fw.append(',');
					fw.append("Type");
					fw.append(',');
					fw.append("LogTime");
					fw.append(',');
					fw.append('\n');
					fw.close();
				} catch(Exception e) {
							
				}
		}
	}.start();
