How does pes itself read this file? There must be a way to open it. Please help me.

What version of PES?
There are already some old topics about some PES games, they mention some modding tools:

Hi
This is a sample file of a pes 2021 patch. I need the files inside it. There are several other files that are protected in the same way. If I find a way to open this file, I will open the rest of the files as well.

This software shows the specifications and content of the file, but does not fully extract it.
