What are these?

Hello,

Recuva recovered these files ...

Can anyone tell me what to do with these files? How to use these files?

I can't find anything that I want. No pictures, no videos, no ....

How can I find sensitive data (passwords, messages ...) from these files?

It looks as if you recovered everything you could find on the disk. The files starting with $ are file system meta files, there is usually no point whatsoever in recovering these files, you can't reinstate them. The other list just looks like a list of files. Who knows what's in them?
