How to create and on what to make a system for sorting files by type?

Question

Programming

I need to create a system that would work on the principle that I put a file of type 1 in a folder, it went to folder 1, I put type 2, it went to 2, and so on.

Absolutely stupid code, works both in Linux and in windows net core 3.1 and higher.
Change OnChanged the full file name arrives there, add your logic.

using System;
using System.Diagnostics;
using System.IO;
using System.Threading;

namespace watcher
{
    internal class Program
    {
       
        private static string _exePath;
        private static int Main(string[] args)
        {
            if (args.Length < 2) return ShowHelp();
            var watchFolder = args[0];
            _exePath = args[1];
            var watcher = new FileSystemWatcher
            {
                Path = watchFolder,
                Filter = "*.*",
                IncludeSubdirectories = true,
                NotifyFilter = NotifyFilters.LastAccess |
                               NotifyFilters.LastWrite |
                               NotifyFilters.FileName |
                               NotifyFilters.DirectoryName,
                EnableRaisingEvents = true
            };
            watcher.Created += OnChanged;

            while (true)
            {
                Thread.Sleep(1000);
            }
        }

        private static int ShowHelp()
        {
            Console.WriteLine("usage: watcher path_to_watch_folder path_to_executable");
            return -1;
        }

        private static void OnChanged(object sender, FileSystemEventArgs e)
        {
            Console.WriteLine(e.FullPath);
            Process.Start(_exePath, e.FullPath);
        }
    }
}

Yes, you can write on anything. But if you are asking such a question, then you should write it in python, not c++.
