Hello,
I am trying to work with raw data in Paraview in Windows 10. The total file is around 15 Gb. However, only a portion of the data is uploaded. Any ideas about how to solve it?
Thanks
Omar

How did you configure the reader? extent/array\_type …
Also what is the format (dimensions, data type) of your raw?

Also, you should not need to apply a slice filter. You can use the slice representation directly to prevent any mesh generation.

Based on what you are saying, what you input is correct but based on the error, it seems that the file is not big enough.
Does file.raw is 4046_4046_727 bytes =\> 11,9 GB ?

I just do it again and this time only one error message appeared, which I believe refers to the z axis that did not uploaded completely, in x-y the images looks ok

I’m really not sure. Are you on a Windows 32 bits rather than a 64 professional?

Just let you know I was able to solve this problem by using a connection of Paraview to an HPC. Thus I presume the problem is a limitation in Windows. I was even able to open a set of data of 80 GB. Some instructions might be helpful for you are the following:

I see this problem in different forums but with no final answer, thus I hope this might be helpful.

Hi, I’ve noticed a similar issue and reported it [here](https://gitlab.kitware.com/paraview/paraview/-/issues/22538#note_1499248). It seems the raw reader may behave differently between the MPI and non-MPI versions.
