<p class="MsoNormal"><span>I wouldn't describe it as a redundant file format, just a redundant file extension (like ExodusII with .e, .ex2, etc.). Actually, looking
through the PV and VTK source code, like Utkarsh did before, there doesn't look to be anything that refers to .pvtm so maybe I'm just remembering things wrong here. Looking back though (</span><a href="https://www.vtk.org/Bug/view.php?id=10498" target="_blank"><span>https://www.vtk.org/Bug/view.<wbr>php?id=10498</span><span></span></a><span>)
it does seem like at one time we used the .pvtm file extension but maybe that was by accident though.
