I have my "Documents" folder redirected to a network share. When I'm out of the office, I still have access to my documents through the Windows offline Folders feature. So in Windows Explorer I can navigate to my Documents folder and all of my files are there. When I reconnect to the office network any changed documents are sync'd with the network version.

In Bridge CS4 and offline, I'm not able to navigate to my Documents but instead get an empty directory.
