Add action to MUI_PAGE_INSTFILES page

Hi guys.

I want to add some actions to MUI_PAGE_INSTFILES page.
Now i have section where i defines some files that i want to extract. I want to add some other actions and add information about it to log(DetailPrint). For example, extract some other files that weren't define earlier.

How can i do this?

Thank you.

Feel free to add more "FILE" commands to your existing section, or create new sections. All sections will be run during the Install Page. Hope this helps.

Thank you.
It was stupid question I have understood.
