I have a solo practitioner client who tells me he is able to keep his documents in Worldox in synch with the same documents in Google Docs. It works like this.
First, you load the Google Word add-in that keeps Word documents in synch with Google Docs.
You create a document in Word, which synchs with Google Docs. You save it and it is profiled in Worldox. The two are in synch.
You open the document from Worldox in Word. It synchs with Google Docs and is saved to Worldox. The two are still in synch.
From a different terminal, you edit the document over the web Google Docs. Now the two documents are different. But when you open the document in Word/Worldox and it synchs up from Google Docs. When you save the document to Worldox, everything is back in synch.
Where this system would break down would be in a larger firm if a single user did NOT have the Google Docs add-in to Word loaded. When that user opens the document and saves it in Worldox, the changes only go to Worldox. If meantime someone opens the document in Google Docs and changes it, you have two conflicting sets of changes and it is unclear which one would “win” the next time it was opened from Word with the Google Docs add-in.
So this is a system that could work on a small scale, but might be iffy in a slightly larger firm if everything was not configured exactly right.
