Granular recovery technology and BE 2012

I thought I read and about to let my boss know that we may need to redesign a customers backup process.

I just want to confirm if GRT works in VMWare backups of say a file server?

I thought I read it did not?

So we have a full backup of a file server using the VMWare way that grabs the whold VMDK file.

So to get a singe file off that backup we need to restore the whole thing somewhere and then copy the file right?
