Can both Mac OS and Windows (via Bootcamp) agree on a unique dropbox folder location? I'm planning to install Windows 8 via Bootcamp. I want to know if it is possible to make a third partition to hold my dropbox folder for my both Mac and Windows dropbox instances? &amp; If possible, what type of partition should I have so that both Mac OS and Windows become comfortable reading and writing to it?

p.s. I'm trying to avoid duplicate syncing and duplicate storage of the same dropbox content in my laptop.
You should use an EXFAT partition. You can set a dropbox folder on an unique location, you'll save a lot of space and bandwidth with that.
