Not responding just opening data

Hello, I’m new to Paraview.

I’m trying to open a tif image stack of CT data. I open Paraview but when I click Open to import the data it just lags and a few minutes later the Open Window appears. When I select my data, which I have downsized from 300dpi to 72dpi tiffs, so its now less than 1 GB in total size, it just stops working. (Not responding)

I have 64GB of Ram running on Windows 10
Intel(R) Core™ i9-10885H CPU @ 2.40GHz 2.40 GHz
Nvidia Quadro RTX 5000

Any help appreciated. Thank you.


Are you able to open juste a few images ?


When the open dialogue window does open I can select say one to one hundred images and they will eventually open. Opening 2000 odd will take some time. Just thought to myself this can’t be normal.


How did you install ParaView ?

I just downloaded it from the Paraview website

You can copy using the button instead of adding images.

  • Please share some data that makes ParaView lagging.
  • Please tru on another computer to see if you reproduce there as well

How would you like me to share the data?
And I’ll try on another computer when I’m back in work next week.

You can share it here if possible or an any platform like wetransfer.

Hi Mathieu,

Here you go 10% of the data.

Thank you

It opens very fast using ParaView 5.11.1 binary release on ArchLinux:

Please try on another computer or also try putting the file in another location (eg, not a network drive, a ssd drive local to the machine).

Hi Mathieu,

Data is on my local HD. I’ll try on another computer when back in work next week.
Or a fresh install. Something isn’t right, before taking the data into consideration, for it to take so long to even open the Open dialogue window, before I even get to direct it to the data.

I will let you know. Thank you for your help so far.


Good point, but that still points to a potential system issue.
