Hi there insearchof,
Looking at the VMX's it appears both VMs are running under a snapshot.
Can you confirm that you haven't redirected the Swap file for these VMs away from the working folder:
Also confirm that /vmfs/volumes/764ff06c-085795c5 is the same datastore as your VMDKs and VMX - this can been seen either from the Shell or by viewing the Datastores Summary page.
Kind regards.
