You can use vtkDataSetReader::ReadOutputType() [1] to tell what type
of data set is in a .vtk file. This member function will return one of
VTK_POLY_DATA, VTK_STRUCTURED_POINTS, VTK_STRUCTURED_GRID,
VTK_RECTILINEAR_GRID, or VTK_UNSTRUCTURED_GRID if the data set can be
read. -1 indicates an error with the output type.
 
HTH,
Cory
