shared folder empty in CentOS VM

[LMHmedchem]

Hello,

I have a VM of CentOS 5.9-x86_64 and it has a shared folder from the windows XP host. The folder is set to automount. There is a shared folder in /media/ that has the correct name, but there is nothing in it.

I think I may need to install guest additions, I don't remember if I have installed it or not. If I select "install guest additions" under the Devices menu, I just get a window opened with the guest additions files in it. How do I check if guest additions is already installed and how do I install if from the command line if I need to?
