VMAN - Using SWQL to exclude VMs residing in a folder in vCenter from the results.

I've tried this with SWQL Studio with no success, but I'm wanting to build an alert to delete snapshots older than X days, but only apply to VMs that don't reside in a particular folder in vCenter so that we don't delete any snapshots on our Citrix MCS templates.

Googling around led me to the attribute, vm.folder.name, but it doesn't appear to be valid.
