Download existing code from org
So now with the org connected, we need to grab all our Apex classes from the org. There is a new icon in the sidebar that resembles the Salesforce.com logo

Click on the icon and head over to Apex Classes
.

Click on the download icon next to it and it'll download all Apex Classes from your org.

Now back in our explorer, under the classes
folder located inside force-app/main/default
, all our Apex classes are available!

Apex Classes downloads all our Classes and Test Classes (Apex Test Classes are Apex Classes with @isTest
annotation). Do the same for Apex Triggers and it'll be available under the triggers
folder
