<div>Yeah, I can certainly see that as a problem. We could change the behavior to be more like other modern readers where you have to list all the files, but that would break backward compatibility and some other features (such as restart case files <<a href="http://www.paraview.org/Wiki/Restarted_Simulation_Readers#Exodus_Time_Series_Case_Files">http://www.paraview.org/Wiki/Restarted_Simulation_Readers#Exodus_Time_Series_Case_Files</a>>
and who knows what else).</div>

</div>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size: 10.5pt; font-family: Calibri, sans-serif; color: black;">I'm thinking it may be easiest to let Python do the heavy lifting on this to figure out the files to read in. You can use glob from
the glob module and then sort the files. So that would look like:<br>
=======<o:p></o:p></span></p>
</div>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size: 10.5pt; font-family: Calibri, sans-serif; color: black;">import glob<o:p></o:p></span></p>
</div>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size: 10.5pt; font-family: Calibri, sans-serif; color: black;">files = glob.glob("z_pinch*")<o:p></o:p></span></p>
</div>
<p class="MsoNormal" style="mso-margin-top-alt:0in;margin-right:0in;margin-bottom:12.0pt;margin-left:.5in">
<span style="font-size: 10.5pt; font-family: Calibri, sans-serif; color: black;">files.sort() # if the order of the files isn't important you can probably skip this<br>
========<o:p></o:p></span></p>
</div>
<p class="MsoNormal" style="mso-margin-top-alt:0in;margin-right:0in;margin-bottom:12.0pt;margin-left:.5in">
<span style="font-size: 10.5pt; font-family: Calibri, sans-serif; color: black;">You can use more advanced regex's in the glob() method to get pickier about the desired files, do a bit of playing around with sort() to get non-default sorting and then play with
the list to get the files you want from them like the last 4 files.<o:p></o:p></span></p>
