I get the error message ERROR: get_file_size: No file size found. when I try to recover a directory.

But it looks that single files located under the same directory can be recovered one by one.

How do I smartly recover a directory? I tried several different directories, but I always get the same error message.

Thank you again. I modified the Python script you linked. It looks almost working. A few output files remain to be like _com.dratapp.recover_Icon but I will investigate it.
