I'm using Windows, and I want to use Dropbox to back up a folder outside my Dropbox directory. So I want to create a junction point from my target directory to my Dropbox folder. According to the NTFS Junction Point article on Wikipedia, also linked from the Dropbox answer:

Junction points can only link to directories on a local volume; junction points to remote shares are unsupported.

I am looking to link to a directory on networked attached storage, which would not be a local volume, I believe. What should I do?

Adding it as a drive letter is not an option? –  surfasb Sep 22 '11 at 23:40

The only thing you can do is create a symbolic link.

I think Symbolic Links only work on Vista+, and I think the target system also needs to support them. –  Ƭᴇcʜιᴇ007 Sep 22 '11 at 20:00
Ah, didn't notice he had specified the OS in the tag. AFAIK, there is no possible solution on Windows XP. –  Zoredache Sep 22 '11 at 20:38
Also, symbolic links casn't be made to network drives, even if they have a local drive letter. –  Hand-E-Food Sep 23 '11 at 0:31
@Zoredache, I gave it another go. I can't create a Junction to a network path. I can create a Symbolic Link to a network path or mapped drive, but I can only navigate it in Explorer. I can't use cd or dir on the link. It may work for Dropbox, I'm not sure. –  Hand-E-Food Sep 23 '11 at 1:14
@Hand-E-Food: The reason you can't use cd or dir on a networked drive is because a symlink contain, literally, a path to its target. Since the cmd interpreter cannot handle UNC paths, it will fail. Try pushd \\UNCpath. –  surfasb Sep 24 '11 at 22:32
