I've disabled versioning on a document library that has grown to 4GB in size for only around 900 documents. Although the versioning is no longer enabled the previous versions of the documents still exist in the AllDocStreams table in the content database. How do I get SharePoint to automatically release the space used by the no longer used versions of the documents?
I'd read somewhere that the unused documents are removed when the user next updates the document and SharePoint determines the previous versions are no longer required. However, I'd prefer to release the space immediately if possible.
