I have Dropbox installed on both Windows 7 and Ubuntu 12.04.3 LTS and there are two separate folders that are being synchronized so there is some waste of disk space.
I would like to have only one Dropbox folder to be synchronized and would like to see a link to this particular folder both on Windows and Ubuntu desktops.

The problem is that my original Dropbox folder (the larger and complete one) is on a separate partition that is not mounted by Ubuntu at startup. How can I have this partition automatically mounted without me interfering ?

Furthermore, if the Dropbox folder on Ubuntu is deleted will it be reflected to my Dropbox account and the online synchronized files? How could this be prevented? I would like to get help on this matter.


You can exclude directories from synchronization by using the Dropbox CLI. You add directories to the exclusion list to disable synching and you remove them from the list to re-enable synching.

$ dropbox exclude add [DIRECTORY]

Partitions that are mounted at system startup are configured by including them in /etc/fstab as shown below. Here's a more detailed explanation that should get you going.

# <file system> <mount point>   <type>  <options>       <dump>  <pass>    
/dev/sda2       /home           ext4    defaults        0       2

Finally, If content is deleted from a synchronized directory the deletion will reflect in Dropbox. However, Dropbox has a versioning system that can be used to undelete content as well as undo changes.

  • I believe selective sync also can be set right from the dropbox software (or at configuring after installation).
