title: Error:the filename directory name or volume label syntax is incorrect, in Delphi 7 CopyFile Function
body: <p>I want to copy files from one folder to another using CopyFile function. The source files paths are stored in a ClientDataSet called "itemsDB". The code is :</p>
  
  <pre><code>Var Source, Dest : String;
  Begin
    itemsDB.First;
    While Not itemsDB.EOF do
    Begin
      Source := itemsDB.FieldValues['FileN'];
      Dest := 'C:\NewDir\'+ExtractFileName(Source);
      if Not CopyFile(PChar(Source), PChar(Dest), False) then
            Showmessage(SysErrorMessage(getlasterror()));
       itemsDB.Next;
    end; 
   end
  </code></pre>
  
  <p>When I execute the code, I get the error message "the filename directory name or volume label syntax is incorrect".
  I verfied all the files paths in the DataSet, they're correct.
  In my example, my clientdataset contains two JPG images "c:\test1.jpg" and "c:\test2.jpg"
  When I tried source := 'c:\test1.jpg', it works perfectly, but when I get it from the clientdataset, it fails.</p>
  
  <p>Thanks in advance       </p>
