How can I work offline and then re-synch with version control in SharePoint?

I am using RoboHelp 11 with SharePoint 2010 for version control. How can I work off-line and then re-synch my files with SharePoint when reconnected?

If I allow the connection to SharePoint to remain while working remotely through VPN, I am constantly annoyed by notices that "the underlying connection is lost."

Thanks!
