[Paraview] Load many VTK from different folders at once

Mon Mar 26 11:47:35 EDT 2012

pvd files can not point to the older style vtk files, they can only
point to the newer xml based vt? (vtu/vtp/vti etc) files.

A script to convert between them build a two element pipeline
consisting of a vtkDataSetReader connected to a vtkXMLPolyDataWriter.
Set the FileNames on both and call Write() on the writer to make the
converted
file.

I mean: I would create this file with the paths in it using a simple script and then I could load this file in paraview to have everything at once… I only need to know whether that may work with .vtp only files or with vtk files as well. In case it would only work with vtk files, is there any way to convert them from vtk to vtp?
