Free Cloud:
Free Cloud is 100% Free but all the files are seperated so you have to see the ads before download the files and the files are shared almost late compare to paid cloud and support cloud.
Paid Cloud:
Paid cloud is similar to free cloud because the files are shared earlier than free cloud also you dont have to see ads and all the cloud files are combined in one archive but remember that you will not get early access to cloud like VIP.
VIP Cloud:
You will get Private cloud + Early access to every cloud files and this will last until you have the plan.
