Other people won’t be able to see your personal file ratings when you share with them. Collaborators of the project will only be able to see their own ratings, not the ratings by the creator nor the other collaborators.
However, as the creator, you will be able to see your collaborator’s ratings as well as an average of the ratings of each file. In addition to this, you can also see the rating of individual collaborators by clicking on the circles with their initials on the right-hand side bar.
This is very useful as you will be able to sort the files by rating and identify the most popular ones.
