Dropbox is a great way to keep data synced between different computers. It is awesome that it has sync applications for both Windows and Linux. This is very useful on a dual-boot computer where it is nice to have data synced and accessible from both Windows and Linux.
This can be achieved by keeping the Dropbox directory on a partition that is accessible from both Windows and Linux. I do this by keeping the Dropbox directory on my NTFS partition that is shared between both OSes.
However, the Dropbox application on Windows insist on the directory being named My Dropbox, while the Linux application insists on the directory name Dropbox. To maintain a common directory between Windows and Linux use the DropboxPath addon on Windows. Use it to setup the Windows application to use the directory named Dropbox created by the Linux application:
$ DropboxPath.exe D:\LinuxShare\Dropbox
