A recursive method for copying files to different volumes

Introduction

Since I found no method in .NET v1.1, to copy files to another volume, I created this recursive method to do it by myself.

Using the code

Here is the code for the FileUtilities class which defines the CopiarMoverDirectorio, CopiarDirectorio, and MoverDirectorio methods. The CopiarMoverDirectorio method contains the main logic, the other two are wrappers.

using System;
using System.IO;

namespace RMORTEGA77.Utils
{
   public class FileUtilities
   {
 
      #region Copy, Move folders - Rodolfo Ortega
      /// <summary>

      /// Recursive procedure to copy or move folder to another volume

      /// </summary>

      /// <param name="d">DirectoryInfo structure of origin</param>

      /// <param name="Destino">Destiny path, including folder</param>

      /// <param name="BorraOrigen">If true, deletes origin</param>

      /// <param name="CreaDirVacios">If true move also if empty</param>

      private static void CopiarMoverDirectorio(DirectoryInfo d, 
              string Destino, bool BorraOrigen, bool CreaDirVacios) 
      { 
         // Get files.

         FileInfo[] fis = d.GetFiles();
         // Create the directory destiny, if CreaDirVacios or contains files

         if ((fis.Length > 0) || (CreaDirVacios))
            Directory.CreateDirectory(Destino);
         foreach (FileInfo fi in fis) 
         { 
            fi.CopyTo(Destino + "\\" + fi.Name);
            // Delete the origin file if BorraOrigen
            if (BorraOrigen)
               fi.Delete(); 
         }
         // Recursive copy children dirs
         DirectoryInfo[] dis = d.GetDirectories();
         foreach (DirectoryInfo di in dis) 
         {
            CopiarMoverDirectorio(di,Destino + "\\" + di.Name, 
                                  BorraOrigen, CreaDirVacios); 
         }
         // Delete the origin dir if BorraOrigen
         if (BorraOrigen)
            d.Delete();
      }

      /// <summary>

      /// </summary>
      /// <param name="Origen">Origin path</param>

      public static void CopiarDirectorio( string Origen, string Destino)
      {
         CopiarMoverDirectorio(new DirectoryInfo(Origen), 
                               Destino, false, false);
      }

      /// <summary>

      public static void MoverDirectorio( string Origen, string Destino)
      {
         try
         {
            Directory.Move( Origen, Destino);
         }
         catch (IOException)
         {
            CopiarMoverDirectorio(new DirectoryInfo(Origen), 
                                  Destino, true, false);
         }
      }
