I am bit confused about whether Opportunity Products count against storage limits or not? We have a lot of Opportunity Products in our system but in the storage tab, we do not see Opportunity Products.
The Salesforce storage guide (http://sforce.co/1pz5B0e) doesn't mention Opportunity Products but neither does it say that it is excluded. Another link (http://bit.ly/1y2U7nl) mentions that Opportunity Products are not counted towards the limit but I am not sure of the authenticity of the data.
Is there a Salesforce documentation which specifically mentions that Opportunity Products are not counted?
