Answer 2

Here is a complete and safe solution!

One thing is that you have to have a 'y' for every file, and it doesn't matter if you have too many, you can have hundreds it only takes seconds and gives error messages that you'll never are able to see.

The temp file creates in the same folder as your bat file and will be erased by the script.

You can also use mdelete * even if dir * shows all files in the sub-folders.
