I find that I regularly download files for one-time use, and I notice that my download folder can add up quickly. I decided to put these files into a folder that is automatically cleaned. In this folder, which I’ve very descriptively labeled ‘CONTENTS DELETED AFTER 30 DAYS,” any file that is more than 30 days old is deleted automatically. I felt that 30 days is plenty of time to re-use most items, and if there’s something I need permanently, I’ve got plenty of time to relocate the file.
Details on setting up this process can be found here.
