One other question, are the snapshot files around 1/2 GB in size?
It depends on how much you use them - the base disks will stay the same but the delta disks will grow over time. Both use the vmdk extension; the delta disks tend to have a bunch of numbers at the end of the name. 1/2 GB seems reasonable for light/moderate use.
Another possibility is these are suspend files (vmem), which will take as much space as you allocated RAM to the VM - again, 1/2 GB seems reasonable.
