There are two simple options to check if your system is full:
Option 1
In your dashboard you will see something similar to the below where you can see how full/empty your system is.
Option 2
Another way you can see how full your system is can be to run a system report. This option can be found in the "Reports" function and then "System Reports". This will give you a more detailed insight as it will show you the status of each box in your system.
