I think my situation is unique in that I am using a Mac and also running windows 7 through Parallels emulation software. My problem is I use Office 2007 and save excel files to my dropbox folders. In order to save space for the dual op systems I needed to eliminate the windows dropbox. The files are synced on the IOS side of things so they exist on the HD. I am not able to access dropbox from the Save menus in Office or through Explorer. I probably dont have the space to sync them twice in both systems. Am I limited to only syncing certain directories or am I missing something?
