Hello Steve Bolduc,
I understand the frustration, and I have the solution. You will want to install a program called Cyberduck tap or click here to download.
It is a cloud storage file explorer once you have it installed and connect your Google account by clicking open connection then click the dropdown menu to select Google Drive and then the connect button. From here you will enter your account details.
You will then want to right-click on the specific folder you would calculate the size of, then left-click on info, then click the calculate button to determine the amount of data stored in a Google drive folder. You will see this info populate in the Size column to the right of the folder name.
Alternatively, Idrive backup works great for calculating specific folder sizes on the fly from their web portal.
