MSIX AppAttach - Disk Space on Host VMs

[BrianPitt]

When attaching an MSIX App via AppAttach to a host VM, the attached application shows up as its own drive and doesnt take up available space on host VM correct?

Trying to decide what size of disk on the host VMs for an AppAttach pool if our users profiles are done via FSLogix and apps are using AppAttach.  Seems like I could go with a small disk size for the host VM.

Is my assumption correct?

I believe that you are correct in your assumption. Attaching the package adds very minimal disk space (mostly for management, not the app assets). The app assets are mounted using an external disk mount to a folder on the local partition.
