overwrite problem with security with recuva

Hello I have a problem with recuva

When I scan with recuva and see the list, I select many files I want to overwrite with confidence and I click Overwrite.

Then when I go to see the files on some files are not overwritten and you always see.

Why does not overwrite all the files with security and skips them?

What you are seeing is the file names, which Rceuva cannot overwrite. The file data has been overwritten (with the exception of very small files).

To remove these file names use CCleaner's Wipe Free Space, with Wipe MFT selected.
