I have a Microsoft Exchange server version 2003 on my job network whose system partition is getting very full. &nbsp;The person who originally installed the server made the system C:\ partition too small. &nbsp;Now the Exchange database resides on another partition on the server which is ok. &nbsp;My problem is that the system C:\ is too full and not allowing for Anti-Virus updates to come in. &nbsp;I notice in the C:\Windows folder there are huge amounts of folders taking up space with the names $ExchuninstallKB#####$ &nbsp;and $NTUninstallKB#####$ etc. &nbsp;Does anyone know what these folders are for and can they be moved or deleted without causing a meltdown?

Folders on MS Exchange server

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
