I have a Buffalo Terastation NAS and a few Windows 7 Pro laptops (one for each member of my family). I have decided to store some of our profile folders (My Documents, My Pictures, My Music) on the NAS and redirect the profile folders to the appropriate location on the NAS. Each user has made their profile folder share on the NAS available for offline use. All of us are experiencing problems with having the latest versions of files when the laptops are offline. I was working on a spreadsheet at home, saved it, closed out of Excel, and then shutdown my laptop. When I turned my laptop on at work wanting to work on my spreadsheet again, I did not have the most current version of it. I've also noticed .tmp files in the same folder as the spreadsheet which seem to cause errors with the spreadsheet at times. All of us seem to be having similar problems to this. Is there a setting I need to change? Is this a Windows problem or a NAS problem? Thanks!
