How does Unidesk calculate space requirements per user?

Unidesk shares a single layer of your O/S gold image (ideally a pristine copy of Microsoft Windows) and single layers of all IT-assigned applications across all users on a single host. So if you have 50 desktops on one host, the space requirement per user will be 1/50th of your O/S layer, plus 1/50th of each application layer (assuming all apps are assigned to all users), plus the space you allocate for each user’s personalization layer (which stores each user’s local profile, documents, directories, and user-installed applications and plug-ins).
