When you create a new AppStack or Writable Volume, the starting point is to take a copy of the existing templates previously attached to the provisioning machine or user's virtual desktop machine.
VMware App Volumes ships with four different types of template as standard, which are:
AppStack application template (20 GB)
Writable Volumes template for user-installed applications (10 GB)
Writable Volumes template for user profiles only (10 GB)
Writable Volume for user profiles and user installed applications (10 GB)
