Colour coding folders will help you to easily identify each folder. It helps it look a little bit more attractive in the process too. As you can see below, folders are all the same colour.
To make each folder stand out, all you have to do is right click the folder and select Edit Properties
It will take you to the folder and a drop down menu will appear for that folder.
You just choose the colour and click OK at the bottom
Repeat the process as many times as you wish
