I am ultimately trying to use data loader to migrate our chatter posts & comments that have files attached to them. They were originally added by uploading directly from computer to the comment. It looks like API version 36 and above, you are supposed to use the ContentVersion object to insert a new file, and then make references to them using the FeedAttachment object.
I am trying to display a list of documents stored in Salesforce CRM Content on a VF page using JQGrid. I used OFFSET for paging. Since the number of records is more than 2000, I wanted to use StandardSetController like I did for some other custom objects.
