How dropbox treats symbolic link

In the cloud the directory structure is not the same as in your computer. Therefore there is no way it will synchronize the symbolic link as it is.
In your computer the link points to the absolute path to your original file/folder. It looks like the following:
Original folder path: /Users/username/home/Documents/Dropbox/MyFolder/
Symbolic link: symlink -> /Users/username/home/Documents/Dropbox/MyFolder/
Since the cloud can't point to this same directory structure it will de-reference it and copy your files (on the cloud) all over again.
Links are great in Dropbox when it points to something outside your dropbox folder. This way the outside files will be copied to the cloud but wont be copied in your computer.
UPDATE: On the matter of relative symbolic links, I guess Dropbox can't sync as it is because your dropbox directory structure may be different from your colleagues.
For example: 
Your structure:          Dropbox/Projects/  
                           - coolfile.txt
                           - SharedDirectory/

Your friend structire:   Dropbox/SharedDirectory/

Relative Symbolic link inside SharedDirectory:  link -> ../coolfile.txt
The link will work your structure but not on your friends.
UPDATE2: links inside Dropbox are also being used to share content from within a shared folder with someone outside that group.

If I create a symlink inside Dropbox folder, pointing to another file also inside Dropbox folder (say, to maintain certain directory stucture), then Dropbox will try to de-reference the symlink and treat it as an normal file, instead of syncing it as a symlink. This could be very frustrating sometimes since I don't want to copies of the same file.

You could set these: alias k = kubectl                         # will already be pre-configured export do = "--dry-run=client -o yaml"     # k get pod x $do export now = "--force --grace-period 0"   # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section .     Question 1 | Contexts Task weight: 1%   You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
