Hi, I need to know if it's possible to upload files from google drive to the repository, and download files from google drive to the repository. If yes, can I have a tutorial or some ideas to start with. thanks in advance
Have you tried using the existing Google Docs integration? It lets you create new documents in Google Docs which are then stored in Alfresco. It also lets you edit docs stored in Alfresco using Google Docs. When you save the Google Doc, the document is versioned and placed back in Alfresco.
What the integration does not cover, however, is starting with a document that exists in Google Docs but does not exist in Alfresco and then uploading from Google Docs into Alfresco. Similarly, when you go from Alfresco to Google Docs, the document is left in a checked out state on the Alfresco side–there is no out-of-the-box functionality that lets you say, "This document should leave Alfresco and only exist in Google Docs".
These functions could be added, of course. It's only a matter of API calls. I do think we have "bulk import from Google Docs" somewhere on our roadmap but, for now, implementing that or the other features not currently covered by the integration is up to you.
