A question about name sorting when open files

I have a .vtk group and I want to visualize them in paraview, I want to see them by 1,2,3… However, somhow it goes with 1,10,11,12… How to fix this?

the screenshot:

Make all numbers two digits long. E.g. rename 1.vtk to 01.vtk, 2.vtk to 02.vtk…

Thank you soooooo much!!!
hahaha, I didn’t notice that
