Sort by size

[HLM]

Dear all,

I have to compare thousands of xml files with identical names and I would easily be able to keep only the largest one, no matter the date. I saw that the comparison displays the same or different size files, but how to display only the largest.
I'm looking for a way to copy the right files easily, there are too many for me to select one by one.
So, if someone has a solution to offer me please.
Thanks for any help.
