You can add items to the context menu (right click) in Explorer. There are a couple of ways of doing that

Add a context menu to the Windows Explorer[^]

.NET Shell Extensions - Shell Context Menus[^]

Or Add your program to the "Send To" folder and capture the command line[^]

I guess the following will do the trick.

C#

using System;
using System.IO;
using System.Windows.Forms;

namespace TXT2MsgBox
{
    static class Program
    {
        static void Main(string[] args)
        {
            if (args.Length > 0)
            {
                FileInfo fi = new FileInfo(args[0]);
                if (fi.Extension.Equals(".txt", StringComparison.InvariantCultureIgnoreCase))
                {
                    string txtContent;
                    using(TextReader tr = new StreamReader(args[0]))
                    {
                        txtContent = tr.ReadToEnd();
                    }
                    MessageBox.Show(txtContent, fi.Name);
                }
            }
        }
    }
}

What you have to do is putting this executable in the 'Send To' folder. the easiers way to do this:

WinKey + R
TYPE: shell:sendto
Press enter
Copy the application here or put a shortcut here

I hope this helps.
