Hi,

I would like a program that surveys a NTFS file system in one drive, for example, drive D in your computer. The survey results must show and count all of files and programs in 3 groups.
group1 : size of files 0 - 10 kilo bytes.
group2 : size of files 10 - 1000 kilo bytes.
group3 : size of files 1000 - 100000 kilo bytes.

The main focus of this project is counting file size of Drive(example) in 3 three groups, that above-mentioned.

What seems to be the problem, nobody is stopping you writing the program/code you want.

Use Google to get ideas and start coding.

Once you have code and run into problems you can always come back here with a more specific question and the community will do its best to help you. Don't forget to post only the relevant code bits that pose the problem as a code dump is not usually helpful at all in getting someone to help/assist you.

Good luck and happy coding.

this is not answer, you could have added it as a comment.. :), who rated it 5 ?

Probably someone who appreciates that it is a valid answer to a rather silly question.

Recursion is your solution :

C#

class Program
    {
        static void Main(string[] args)
        {
            DirectoryInfo tDir = new DirectoryInfo(@"C:\");
            string Pattern = "a";
             TraverseDirs(tDir, Pattern);
            Console.Read();
        }
         private static void TraverseDirs(DirectoryInfo dir, string Pattern)
         {            // Subdirs
            try         // Avoid errors such as "Access Denied"
            {
                foreach (DirectoryInfo iInfo in dir.GetDirectories())
                {
                    if (iInfo.Name.StartsWith(Pattern))
                        Console.WriteLine("Found dir:  " + iInfo.FullName);
                     TraverseDirs(iInfo, Pattern);
                }
            }
            catch (Exception)
            {
            }
             // Subfiles
            try         // Avoid errors such as "Access Denied"
            {
                foreach (FileInfo iInfo in dir.GetFiles())
                {
                    if (iInfo.Name.StartsWith(Pattern))
                        Console.WriteLine("Found file: " + iInfo.FullName);
                }
            }
            catch (Exception)
            {
            }
        }    
}

This is not exactly what you want, but I hope you can figure out based on this, some reference is also provided below.

You asked for code? Here is it: (just copy to a console project and replace Program.cs with the following code)
(Keep in mind that file sizes on drives are not meassured like 1kB = 1000B but 1kB = 1024B, ...)
Counting can take some time on big drives with a lot of files!

C#

using System;
using System.IO;

namespace CountFiles
{
    class Program
    {
        static void Main(string[] args)
        {
            string strRootPath = @"D:\";
            int iCount10kB = 0,iCount1000kB = 0,iCount100000kB = 0, iCountBigger = 0;
            CountFiles(strRootPath,
                ref iCount10kB, ref iCount1000kB, ref iCount100000kB, ref iCountBigger);
            Console.WriteLine("Results for root directory {0}", strRootPath);
            Console.WriteLine("Files 0kB - 10 kB:           {0}", iCount10kB);
            Console.WriteLine("Files 10kB - 1000 kB:        {0}", iCount1000kB);
            Console.WriteLine("Files 1000kB - 100000 kB:    {0}", iCount100000kB);
            Console.WriteLine("Files bigger than 100000 kB: {0}", iCountBigger);
            Console.ReadKey();
        }

        static void CountFiles(string strRootPath,
            ref int iCount10kB, ref int iCount1000kB, ref int iCount100000kB, ref int iCountBigger)
        {
            try
            {
                string[] astrFiles = Directory.GetFiles(strRootPath);
                foreach (string strFile in astrFiles)
                {
                    long iFileLength = new FileInfo(strFile).Length;
                    if (iFileLength < 10000)
                        iCount10kB++;
                    else if (iFileLength < 1000000)
                        iCount1000kB++;
                    else if (iFileLength < 100000000)
                        iCount100000kB++;
                    else
                        iCountBigger++;
                }
            }
            catch
            {
                // ignore file access errors
            }

            try
            {
                string[] astrSubDirs = Directory.GetDirectories(strRootPath);
                foreach (string strSubDir in astrSubDirs)
                {
                    CountFiles(strSubDir, // recursion
                        ref iCount10kB, ref iCount1000kB, ref iCount100000kB, ref iCountBigger);
                }
            }
            catch
            {
                // ignore directory access errors
            }
        }
    }
}
