title: Json file not found after the Build
body: <p>I'd like to find where the json file is saved. In the editor mode I can find it. However, when I make the build of the game, I cannot find it. </p>
  
  <p>I'm using this script to save the game:</p>
  
  <pre><code>using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  using System.IO;
  
  public class DataManager : MonoBehaviour
  {
      public GameHandler data;
      private string file = "player.txt";
  
      public void Save()
      {
          string json = JsonUtility.ToJson(data);
          WriteTopFile(file, json);
      }
  
      public void Load()
      {
          data = new GameHandler();
          string json = ReadFromFile(file);
          JsonUtility.FromJsonOverwrite(json, data);
      }
  
      private void WriteTopFile(string fileName, string json)
      {
          string path = GetFilePath(fileName);
          FileStream fileStream = new FileStream(path, FileMode.Create);
  
          using (StreamWriter writer = new StreamWriter(fileStream))
          {
              writer.Write(json);
          } 
      }
  
      private string ReadFromFile(string fileName)
      {
          string path = GetFilePath(fileName);
          if (File.Exists(path))
          {
              print(path);
              using(StreamReader reader = new StreamReader(path))
              {
                  string json = reader.ReadToEnd();
                  return json;
              }
          }
          else
          {
              Debug.LogError("File not found");
              return "";
          }
      }
  
      private string GetFilePath(string fileName)
      {
          return Application.persistentDataPath + "/" + fileName;
      }
  }
  </code></pre>
