You can easily create folders to get a better overview of the board's documents. It is also possible to have subfolders, so for example, you can have a folder named "Accounting" and within it, folders for 2018, 2019, 2020, etc.

1. When you are in "Files," click on the blue button with a "+" and then click on "Create folder."

2. Give the folder a name and click on "Create folder."

3. You can now add files by dragging them over from a folder on your computer or by selecting them from a folder on your computer.
