If you are expecting documents from parents, it can be easier for you to receive all of them in the same place. To do so, just right-click on a folder and choose "Get info". A small window is showing allowing you to change the folder's name, add a description, and at the top, making the folder accessible for parents.

When surfing on the last 3 columns you can visualize the type of file anytime (no matter what name it has), who has access to it and its size.
