Formatted video files

[is0]

Hello

I have formatted a SD card. They are all video files made with my sony a7iii. And also formatted the card with my sony.
I've read alot about it and many could recover their files, or at least a part of it. I also didn't use the card after formatting, so nothing new has been filmed.

But I don't understand:
if the files are formatted and the card keeps them anyway (only we can't see it if we open the mapstructure of the card) and even overwrites my specifiec files I want to recover with newer files then why Recuva (or any other program) can't find ANY file? Old or new? How come some people can have their files back and in my case none files can be found? 

I've done the recovery and he only find some bin files or other files with 0kb.

Thanks for the advice.
