Automatically delete an included folder

[Harry_Cover]

A correspondent frequently sends me emails containing folders as attachments.
I manually download folders files to the Downloads folder.

These folders contain useful documents, but also the same useless identification folder, with the same name.
How could I tell Hazel to automatically move this folder to the trash?

Thanks in advance for helping.

Are the useful documents inside this folder? Are you moving those documents out of the folder?

Thanks for quick replying.
Both are good but moving the useful documents wood be still better.

So the documents are in the folder? Can you provide me with a concrete example demonstrating the file/folder hierarchy?
