One of the features of File Cabinet pages in Google Sites, is the option to add descriptions to documents. This option isn’t readily visible. We need to move our mouse over to the right of a file until we see a yellow highlight. Once the highlight appears, click on the highlighted area.
An Edit Description box will open.
Provide a description for the file and click Save.
The description will display to the right of the file. The description can be edited by clicking on it.
