This is working fine but i realise that the file will be overwrite every time a new game is play which is not i want. I want to maintain the data. Instead of overwrite the data, i want to add on to the data. Any thing bother me is regarding, how we know this file is belong to which players. Is it any possible way i can solve this issues? Like this data in this file is the record play by may… Please help!!! :((

using UnityEngine;
using System.Collections;
using System;
using System.Text;
using System.IO;

public class Monitor : MonoBehaviour {
	
	String path;
	String fileName;
	String playerName;
	int id =1;
	// Use this for initialization
	void Start () 
	{
		fileName = "/Monitoring.txt";
		playerName = playerControl.playerName;
		print(gameControl.previousWord1);
	}
	
	// Update is called once per frame
	void Update () 
	{
		//string messageToAccess = gameControl.previousWord1;
		path = Application.dataPath + fileName;
		
		using(FileStream fs = File.Create(path))
		{
			AddText(fs, "PlayerName: " + playerName);
			AddText(fs, "

================================");
AddText(fs, "
" + id);
for(int j = 0; j < gameControl.radical00Store.length; j++)
{
AddText(fs, " " + gameControl.radical00Store[j]);
AddText(fs, " " + gameControl.radical0Store[j]);
AddText(fs, " " + gameControl.previousWord1[j]);
}
AddText(fs, " " + gameControl.wrongMatch + "
");
}
id++;

		 //Open the stream and read it back.
        using (FileStream fs = File.OpenRead(path))
        {
            byte[] b = new byte[1024];
            UTF8Encoding temp = new UTF8Encoding(true);
            while (fs.Read(b,0,b.Length) > 0)
            {
                Console.WriteLine(temp.GetString(b));
            }
        }
	}
	
	
	private static void AddText(FileStream fs, string value)
    {
        byte[] info = new UTF8Encoding(true).GetBytes(value);
        fs.Write(info, 0, info.Length);
    }

Look at File.Open (instead of create.) It has an Append option to add to the end. But, in practice, you rarely want to write to the end - you want to modify what’s there. To do that, read the file into an array make changes (like add 1 to games played,) then erase the old file and write it all back.

For names, you can make the name part of the fileName: MonitoringStan.txt, and have 1 file for each player. Most people would have one file look like: name, stats for name; 2nd name, stats for 2nd name; … . Then have the reader and writer know to keep reading/writing names until EOF.
