Using TSHFileOpStruct to copy files

Hi, I have a problem. When I copy a file from a ShellListView1 (Drive c: for instance) to another drive (D: for instance), and the file I want to copy is already on D:, the file is not overwritten. No questions are asked wether to allow to overwrite te file with the newer one. How can I do this ?
Here is the code.

procedure TJawsieback.SpeedButton4Click(Sender: TObject);
 var FOS: TSHFileOpStruct;
     A, B: string;
     i: integer ;
begin
try
B:= ShellTreeView2.Path;
SpeedButton3.Enabled:= False;
 ShellTreeView2.Root:= B;
 for i:= 0 to ShellListView1.Items.Count -1 do begin
  if ShellListView1.Items.Item[i].Selected = True then begin
   Label4.Caption:= 'Schrijven gegevens naar de Bestemmings-schijf';
   A:= ShellListView1.Folders[i].PathName ;
   DirectorySize(A);
   GetHugeFileSize(A);
   Label5.Caption:= IntToStr(DirectorySize(A));
   Label16.Caption:= IntToStr(GetHugeFileSize(A));
   Vrij:= DiskFree(Datamodule1.BackupSchijfnummer.Value);
   Label6.Caption:= IntToStr(vrij);
          with FOS do begin
           wFunc:= FO_COPY;
           pFrom:= PChar(A + #0);
           pTo:= PChar(B + #0);
           fFlags:= FOF_NoConfirmMKDir;
           SHFileOperation(FOS);
           ShellListView1.Items.Item[i].Selected := False;
           Vrij:= DiskFree(Datamodule1.BackupSchijfnummer.Value);
         end;
  end;
end;
finally
 ShellListView2.Update;
 ShellTreeView2.Update;
 SpeedButton3.Enabled:= True;
 SpeedButton4.Visible:= False;
 SpeedButton1.Enabled:= True;
 Label6.Caption:= IntToStr(0);
 Label5.Caption:= IntToStr(0);
 Label4.Caption:= 'Backup voltooid';
end;
end;


Thx a lot

Make this minor change:

   fFlags:= FOF_NoConfirmMKDir or FOF_NoConfirmation;

I believe the file will be written over with no notification. (That's what you want?)

Hi, I tried it and it works fine for a single file, but I still have another problem: When I copy a directory from C: to D: , the first time everything is OK, even when I change the content of a file inside the directory on C: ; but when I delete for instance a file in the directory on C: and copy the directory to D: (where the first copy resides) , the file I deleted on C: is still visible in the directory on the D:. So I suppose the directory on the D: is not overwritten (?!).

thx
