Your code works fine for me (Fedora). Are you calling the program with:

./TestProgram Directory

or some other argument?

What operating system are you using?

Try hard coding a directory:

#include <vtkSmartPointer.h>
#include <vtkDirectory.h>

#include <vtksys/SystemTools.hxx>

int main(int, char *[])
{

  vtkstd::string inputDirectory = ".";
  vtkSmartPointer<vtkDirectory> directory =
    vtkSmartPointer<vtkDirectory>::New();

  int opened = directory->Open(inputDirectory.c_str());

  if(opened)
   {

    int numImages = directory->GetNumberOfFiles();

    for (int i = 0; i < numImages; i++)
      {
      vtkstd::string filename = directory->GetFile(i);
      vtkstd::string ext =
        vtksys::SystemTools::GetFilenameLastExtension(filename);

      }
    }
}

Thanks,

David
