We can use the ContentVersion object/entity to create, query, retrieve, search, edit, and update a specific version of a Salesforce file. We cannot delete it though. We can use the ContentDocument object/entity to retrieve, query, update, and delete the latest version of a Salesforce file.

Delete action/operation is not supported on the ContentVersion object/entity. So, Content Document should be queried and deleted which in turn will delete the Content Versions.

Supported Calls/Actions on ContentVersion object/entity:

create(), describeLayout(), describeSObjects(), query(), retrieve(), search(), update(), upsert()
