Dropbox is a great tool for synchronising files across multiple computers or even for just keeping a copy of important documents backed up remotely but occasionally you might want to use it to sync a folder that you don’t want to keep in the Dropbox folder structure. By default Dropbox only synchronises folders in your automatically created Dropbox folder.
Fortunately there is a quick solution to this using symbolic links. A symbolic link is a special file that points to a file or folder somewhere else on your disk. You cannot create a symbolic link from the Finder it is created using the ln command in a terminal window.
Open a terminal window and type the ln command as in the following code excerpt:-
ln -s /sourcedirectory ~/Dropbox/sourcedirectory
This will create a symbolic link in your Dropbox folder called sourcedirectory which points at the original directory located at /sourcedirectory.
To verify if this link is working open a Finder window and you should see a folder in your Dropbox folder called sourcedirectory with a small black arrow in the corner of the folder icon. If you double click this link file your Finder window should open the original directory.
If you later decide that you no longer want this directory synchronising with Dropbox just delete the link file in the Dropbox folder with Finder.
