title: Use the standard "overwrite" dialog with custom information
body: <p>I am writing a utility copying files to/from remote drives (eg SkyDrive). When I'm about to overwrite a file, I pop up a regular "file exists, do you want to overwrite Y/N" message box; is it possible to use the standard Windows file overwrite dialog instead? With the three options (copy and replace, don't copy, copy but keep both) and the more detailed size / date information? Or should I just write my own form to duplicate that? (To be honest, I've been searching for this for two days, it would probably have been much faster to just write my own.)</p>
  
  <p>To clarify: I need to show up that dialog <em>when I choose to</em> - sometimes I don't want to show it and just want to overwrite the file.</p>
  
  <p>If at all possible, I would prefer for this to work in C# / .NET; however, if only an unmanaged solution exists I'll take that too.</p>
