  1. Download Hazel app.
  2. Set up a new rule containing the following for your downloads folder.

    If Any
    Name contains “your-company-name”

    Do the following..
    Rename with pattern [date added]_[creator][extension]

Paperless rule for Hazel +

What I realized was that each of the above types of documents could easily be identified by my unique account number with each company. And so I set up rules in Hazel to look at the contents of a document, and depending on which criteria that document matches Hazel renames the PDF accordingly and then files it into the proper folder on my Mac.

Smart. I need to add this to my Hazel rules for my paperless setup.
