Sync only 1 kind of filetype to another folder?

This is the structure

PDFs & Audio (Local) > Greg McKeown > Essentialism.pdf and Essentialism.mp3

How do I sync the entire structure and its contents without the .mp3 but just the .pdf? I'm trying to sync

PDFs & Audio (Local) to PDFs & Audio (Cloud) copying all the folder structures and the .pdf but without the .mp3.

You can't use the Sync action since that does everything. Instead, you need to have a rule process the PDF. In the copy action, there is an option to copy over the folder structure. Now, to get Hazel to go into subfolders to get to the PDF in the first place, you'll need to have another rule to tell Hazel to do that. Check the sticky article at the top of this forum as it describes just that.
