I use Xubuntu, what is the path command needed to access a folder shared by another Xubuntu user on the same pc?

I followed the suggestion found on this site (link below), which seems to answer my question. However, when the other user tries to access the shared folder on my Desktop, from his Desktop he gets a permission denied error. The user is in the Sudo group but I want him to avoid using root if at all possible. The above explains that a 'data' folder, the contents of which should be copied to the shared folder, is not necessary. I therefore created a folder on my Desktop 'SHARED' and then followed the instructions.
