Doubt: Access explorer conent from Share

Hi all

Just a question I would like to raise please. We are using alfresco 4.2.e and have some customizations done in alfresco explorer, content type definitions, workflows... All the content items are stored with their types and aspects in Alfresco Explorer 4.2.e. My question here would be, once we upload a document to Alfresco Explorer, will it be accesible from the Alfresco Share interface??, if so, how? Is there any way to get access to the Alfresco Explorer repository from Alfresco Share in 4.2??

Thanks a lot
