While there is a feature to be notified via of new files/folders or activity in the account, there is no feature that indicates if a file is new since you last viewed the folder. With having so many files, it can be difficult to know what has or hasn't been viewed and it is cumbersome to go through the setting in each individual file to see the upload date. The automation to separate documents into folders by upload date is a slight workaround but adds complexity to view all needed files. Either a symbol of "This is new since last opened" OR adding in the upload date directly under file view would be extremely helpful.
