Moving files within the PDM vault

I am setting up Workgroup PDM and having a play around before I start using it for real. Is it possible to move model files between vault project (sub)folders? For example if I wanted to create another subfolder within a project and move some files to that. I can't seem to move files that are within the vault. Surely they're not locked into where they are initially saved.

Thanks,

Mark
