[Paraview] Fastest way of getting Max/Min from multiple files.

[Brian Curtis]

I have code that reads in multiple .vtk (legacy VTK) binary files. 
Currently I am looping through viewtimes and grabbing the range and 
saving the value if it's higher than the previous value (and lower..). 
I've looked quite a bit through tutorials and other threads and haven't 
found anything to this sort, but In order to save processing time, is 
there a simple way to grab a range for all time steps and not each file 
one by one?

Thanks,
