Solution 2

YES, you can compress folder(s) and file(s) without any third party tool.

.NET provides classes for compression in System.IO.Compression namespace.

Try it. best of luck...

using System.IO.Compression;

i m using this but getting error like this

Error 1 'System.IO.FileStream' does not contain a definition for 'CopyTo' and no extension method 'CopyTo' accepting a first argument of type 'System.IO.FileStream' could be found (are you missing a using directive or an assembly reference?)

C#

using System;
using System.Collections.Generic;
using System.Text;

using System.IO;
using System.IO.Compression;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string sFileToZip = @"D:\code.txt";
            string sZipFile = @"D:\code.zip";

            using (FileStream __fStream = File.Open(sZipFile, FileMode.Create))
            {
                GZipStream obj = new GZipStream(__fStream, CompressionMode.Compress);

                byte[] bt = File.ReadAllBytes(sFileToZip);
                obj.Write(bt, 0, bt.Length);

                obj.Close();
                obj.Dispose();
            }
        }
