Are they all in one folder? No exception handling, but this works:

csharp

static void Main(string[] args)
{
    System.IO.DirectoryInfo di = new System.IO.DirectoryInfo("..\\..\\blah");
    foreach (System.IO.FileInfo fi in di.GetFiles("ORD*"))
    {
        string origName = fi.Name;
        string newName = origName.Insert(origName.Length - 3, ".").Replace("RD", "");
        System.IO.File.Move(System.IO.Path.Combine(fi.DirectoryName, origName), 
            System.IO.Path.Combine(fi.DirectoryName, newName));
    }
}

That's not the whole thing...this is though.

csharp

namespace Renamer
{
    class Program
    {
        static void Main(string[] args)
        {
            System.IO.DirectoryInfo di = new System.IO.DirectoryInfo("..\\..\\blah");
            foreach (System.IO.FileInfo fi in di.GetFiles("ORD*"))
            {
                string origName = fi.Name;
                string newName = origName.Insert(origName.Length - 3, ".").Replace("RD", "");
                System.IO.File.Move(System.IO.Path.Combine(fi.DirectoryName, origName), 
                    System.IO.Path.Combine(fi.DirectoryName, newName));
            }
        }
    }
}

CODE namespace Renamer { class Program { static void Main(string[] args) { System.IO.DirectoryInfo di = new System.IO.DirectoryInfo("c:\\todos\\inbox\\finished"); foreach (System.IO.FileInfo fi in di.GetFiles("CF*")) { string origName = fi.Name; string newName = origName.Replace("CF", "CNF").Replace(".",""); System.IO.File.Move(System.IO.Path.Combine(fi.DirectoryName, origName), System.IO.Path.Combine(fi.DirectoryName, newName)); } } } }
